xenodm crashes frequently

[andinus]

- pcmanfm crash
- start xenodm
- run pcmanfm
- xenodm crashes

- elfeed crash
- start xenodm
- run elfeed & do some CPU intensive work (?)
- xenodm crashes

Elfeed has around 3500 entries & when I click page down twice in a row,
xenodm crashes. There is no crash when I limit the entries to ~500. This
is not due to memory exhaustion. Also, I frequently load 2-5x size files
to buffer & I can spam page down on them, Emacs doesn't crash.

`.elfeed/' has around 800 files.

================ files ================

[/var/log/xenodm.log] https://paste.debian.net/hidden/ef053f15/
[/var/log/Xorg.0.log] https://paste.debian.net/hidden/5b8a5784/
[dmesg.boot] https://andinus.tilde.institute/0Jm1...vx85LVcHj3K0Eh

I also have `ktrace' of pcmanfm when it crashes & emacs core dump when
xenodm crashed. But both have sensitive information, pcmanfm ktrace
contains whole files & emacs dump has whole buffers. I can run things on
them & send the output though.

================ versions ================

- OpenBSD 6.8
- pcmanfm 1.3.1
- GNU Emacs 27.1

It's after new or upgrade install?

[andinus]

This is after a new install.

I had the same with pcmanfm, it crashed often. In the end switched to Xfe (Caja is good too).

[andinus]

Yes, I switched to Caja & I'm running elfeed in xterm.

xenodm also crashes when I run `telnet mapscii.me`. Doesn't crash when I run it in kitty or on remote host in xterm.

I forgot to mention that in my case the session itself wasn't actually affected, only pcmanfm crashed. I use xenodm and otherwise awesomewm and they were running fine, even if the file manager crashed.
I just tested telnet mapscii.me in xterm and no issues so far. Wondering if .xsession-errors might have useful hints. Am I wrong that there used to be a pcmanfm package? At least there isn't one available right now. It looks it's only available in ports. (As a sidenote: I could not set as user things like "list view" or "show hidden files" in Caja via Preferences. It worked only if I started Caja with doas.)

[andinus]

Thanks for the hint, looks like it was hitting some limits: https://paste.debian.net/hidden/c1c46d21/ (~/.xsession)

I ran `xterm', `firefox-esr' and `emacs elfeed' together to make it crash. It says "Fatal IO error 35 (Resource temporarily unavailable) on X server". I wasn't able to replicate the `telnet' issue on this run.

I'm able to set those options in Caja.

[bradley]

Similar crashes happened to me on Linux before on an older hardware (I guess more RAM is helpful in cases like that). So far no such experiences on OpenBSD.

[andinus]

This issue has been solved, it was unrelated to all these programs. Switching from the "intel" driver to "modesetting" driver fixed it. I wrote about it here: https://andinus.nand.sh/writings/fat...n-openbsd.html
