Default Weird freezing when downloading through ftp

Hello all.

Sometimes when I am downloading a large .iso file (hundreds or few thousands of MB) through ftp from a local NAS, the system freezes. X freezes, CPU fan goes a little higher and I cannot recover the system, so a hard button reset is needed. I tried to write blindly boot sync just in case, but to no avail.

It happens either using ftp from shell or through Konqueror (I have not tried anything else for these seem quite different tests).

Update:

It has happened the same when transferring a large file (700 MB .avi file) from a desktop USB disk to the main system disk.

I suspect it is not a ftp issue, but a disk issue. I use ffs with softupdates enabled.

However, when I use dd to create large random files it does not fail.

Hi. I'm sorry you're having trouble. Unfortunately, it isn't clear from your post what hardware and software you're running. And while I may not be able to solve your problem, I can't provide any insights into possible root causes, solutions, or circumventions without more information. The questions that immediately come to mind are:
  1. What version/flavor of OpenBSD are you running?
  2. What architecture are you using?
  3. What NIC hardware is in use?
  4. Which ftp client are you using from the shell? The built-in ftp(1)?
  5. If the external storage is NAS-attached as described, why are you using FTP instead of NFS or SMB/CIFS?
  6. Have you set the ddb.console sysctl to permit keyboard entry into ddb(4) during a hang? If so, when in a console rather than X, have you been able to enter ddb with the keyboard sequence that is applicable to your architecture?
  7. Have you inspected /var/log/messages for any possible hints in logged messages about the problem, such as exhausting mbufs?
  8. Have you run netstat(8) with the -m, -i, or -s options during transfers to watch for network related problems as the transfers are in progress?
A dmesg would answer the first three questions.

OK, now that I know you have a problem you suspect is drive related:
  • Review /var/log/messages* for any kernel messages regarding drive errors: timeounts, "soft" errors, etc.
  • Install smartmontools and request information from the drive's electronics on possible problems or errors. See http://en.wikipedia.org/wiki/S.M.A.R.T. and then use smartmontool's smartctl(8) with the -a option to get a complete report on the suspect drive from the on-board electronics.
I started to write a long treatise on hard drives and then stopped. Let's see what you can learn about the drive with this much information.

Thanks for answering. The basic system arquitecture and OS is:

Quote:
OpenBSD 5.3 GENERIC.MP#2 amd64
However it also happened in 5.2, and I am not sure about 5.1, so I do not affirm it in the last.

Thanks about the ddb.console tip, I had seen an old post about it, but I misunderstood it. I will monitorize de disk with the smartmon tools, but this disk had been on W7 from 2009 till this year and never failed (Samsung, 512 bps), that is what puzzles me.

No trace of error in /var/log/messages (and rotated) except for the boot messages about / not properly unmounted and softraid0 devices not shutdown properly.

This disk/transfer thing is the only thing that bothers me about this OS in my machine, so I will track it down.

Your problem might not be the disk drive; this is your assumption. My recommendations should help determine if the drive is at fault.
  • I recommended checking kernel message logs as they will not be seen unless you are using the console or have an xconsole(1) window open.
  • I recommended checking SMART logs on the device, as the device may have information not presented to the OS.

Maybe you've corrupted things with fsck after forcing a shutdown? Make a new user and try that profile out, that's what I've done - essentially I've cleaned out old .* config files in my home directory. The gist of it, is that killing the power and forcing an fsck check always has the potential to corrupt data. I have found on my desktop that means my .* config files in my home directory are unreadable. OpenBSD will then attempt to repair these files it seems, which takes forever. I have a sneaking suspicion that if you waited long enough things would mostly get repaired, but frankly OpenBSD is not intended to run as a desktop and you've said this has been a problem for a while. Also, is this the machine where 'apm -z' is not working?

I do recall some traffic on misc@ many years ago where somewhat similar claims were being made, but these discussions have subsided for quite some time now. As an example, the most recent mention I can find in the misc@ archives is over a year ago:

http://marc.info/?l=openbsd-misc&m=133657680618500&w=2

...but as jggimi has already mentioned, there is simply too little information provided here for us to give anything more than general comments at this point. My suggestion to Martillo is to attempt to isolate a more substantial test case & submit a problem report. Be aware that the first question the project developers will ask is whether this problem still manifests itself in -current. Testing whatever you discern in -current will likely also receive faster attention. Likewise, recognize that your goal is to provide a repeatable test case. Anything less is frankly insufficient.

Lastly, information on submitting problem reports can be found at the following:

http://www.openbsd.org/report.html

I have been running OpenBSD successfully in a desktop configuration for many years, so I don't agree with your assessment, vanGrimoire. If you wish to discuss this further, please start a new thread, as this is off-topic from what the OP initially asked.

And, I think vanGrimiore will get a great deal of vitriolic push-back from developers if that opinion were voiced on misc@. Many developers have spent countless thousands of hours ensuring that OpenBSD can be a useful and convenient workstation OS.

Sorry, I meant no harm.

Only trying to point out that I've noticed a slow down at points as well and why. I love my desktop, but it has given me more problems than a base install, in fact I've never run fsck on a base install. I've been using obsd for 3.5 years now and love the beast. I did mix martillo with another user, so oops. I will slow down a bit.

for me `lynx ftp://ftp.openbsd.org/pub/OpenBSD/5.3/packages/amd64/`

takes 2min. 13seconds at 1.5 Mbps

slashdot for comparison takes 13secs

I tend to think you are comparing apples & oranges. Given that your test involves different sites at different distances (verify with traceroute(8)...), the numbers mentioned above aren't necessarily measuring the same thing.

Likewise, no mention has been made as to whether the filesizes or protocols are equivalent.

Frankly , OpenBSD is now most successful both as a firewall & as a desktop OS (straighforward installation .. stability .. localization .. variety .. (I hope there will be a gnomebase -in the fashion of kdebase- lightweight with few deps)

It also depends on the geographic distance. I am located in the Netherlands and have optic fiber 100Mbit up/down.

Code:
$ time echo ls | ftp -a ftp://ftp.bit.nl/pub/OpenBSD/5.3/packages/amd64/ >packages.nl
    0m1.73s real     0m0.03s user     0m1.53s system

$  time echo ls | ftp -a ftp://ftp.eu.openbsd.org/pub/OpenBSD/5.3/packages/amd64/  >packages.se
    0m8.18s real     0m0.04s user     0m1.52s system

$  time echo ls | ftp -a ftp://ftp.openbsd.org/pub/OpenBSD/5.3/packages/amd64/ >packages.ca
    0m4.47s real     0m0.01s user     0m1.29s system
Here it is rather strange that the download from Canada is faster than the one from Sweden

This is comparing apples with diving boards. Different protocols (FTP vs. HTTP), different amounts of data being searched for and returned, different server farm infrastructures, and the servers are located in different countries. And the FTP server being queried isn't running OpenBSD. But you're comparing workstations.

If you want to compare different workstation OSes, try comparing the same transaction. Hint: OpenBSD will probably not be the fastest performer. It will, however, likely be more stable, likely be the easiest and quickest to install and maintain, perhaps the easiest to understand, and unless you misconfigure your applications or install insecure ones, is likely to be the most secure from external attack vectors.

Situation update:

I have tried another methods to access the NAS (BTW, a Home Desktop Cloud Edition by Iomega :facepalm: ) and found CIFS reliable; smbget and smbclient work so far with good performance.

Peace of mind for now.

Situation update:

smbclient started to fail when putting a large file, but in a different way: the network card ceased working without notice. No ping, no host or dig worked either. Rebooted two times and the same happened. For the record: I rebooted to NetBSD, and smbclient worked fine.

So I looked for another cause and discovered that the rear fan and the power fan where clogged with dirt and the airflows were minimal. I had also noticed a raise of temperature in the last few weeks. An air duster put an end to the clogging and smbclient worked fine again...

...until now that has stopped working again. It seems it was not the temperature.

This is -release. Which patches have been applied? Did you customize src/sys/arch/amd64/conf/GENERIC.MP?

I'd love to see the output from the following commands if the system is still operational after the failure of a put:

$ ifconfig
$ netstat -ni
$ netstat -nm
$ netstat -ns

And, if PF is used on the platform:

# pfctl -s info
# pfctl -s memory

Last edited by jggimi; 17th June 2013 at 12:07 PM. Reason: $ -> # for pfctl, and added -s memory

The system is amd64 5.3 patched until 007. No custom patches.

The network interface I use is msk0. The other one (msk1) has an inverse RJ45 cable attached (but not connected to anything else).

I could reproduce the smbclient malfunction and the loss of network at first intent. The outputs of the commands are:

$ ifconfig

Thank you very much! The good news:
  • You aren't using jumbo frames -- which sometimes can be a problem for network components.
  • The link is active, running 1000BaseT full-duplex and there are no local LAN errors recorded by the NIC (and confirmed by no IP protocol problems).
  • There is no issue with network capacity: neither mbufs nor PF state table entries show a problem.
I do see what appears to be some TCP windowing and retry issues -- it is just a guess on my part but packet normalization within PF ("scrub") may be incorrectly configured. See the Packet Normalization section of pf.conf(5) for details.
