em driver problems? taskq em goes up to 100% CPU
Hi,
I seem to have the following problem: There's two FreeBSD boxes that do ipfw nat. I got two Intel cards (Intel <EXPI9404PT> PRO/1000 PT Quad Port (OEM) PCI-E x4 10/100/1000Mbps) - one for each box, since the msk cards that boxes had onboard had problems like "kernel: msk0: Rx FIFO overrun!". em cards solved the FIFO problem, BUT: there's now a problem with spontaneous peaks of system load: irrelatively to anything I can guess the system processes taskq em0/em2 begin to eat 100% of CPU (and stay like that for about 1 or 2 minutes). And when that happens, traffic stops to pass through the box. The problem is there on both boxes. I tried upgrading both of them to RELENG_7_0, RELENG_7_1 (RC2 currently), RELENG_7 - the problem remains. Any suggestions on what can I do to solve the problem? I have just no idea on what causes that and what to do to fix it. I would really appreciate your help.. And just to be thorough, here's my kernel options: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=400 options IPFIREWALL_DEFAULT_TO_ACCEPT options IPFIREWALL_FORWARD options IPFIREWALL_NAT options LIBALIAS options DUMMYNET options IPDIVERT fastforwarding is on, polling is off: net.inet.ip.fastforwarding: 1 em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING, VLAN_HWCSUM,TSO4> ether 00:00:10:01:1:01 inet 10.1.1.1 netmask 0xffffff00 broadcast 10.1.1.255 media: Ethernet autoselect (1000baseTX <full-duplex>) status: active |
