Summary:
Kernel 2.2.19 hang [stuck on TLB IPI wait (CPU#0)]
Description:
After recently upgrading the kernel on a production server to
kernel 2.2.19 with the reiserfs patch and kernel-patch-2.2.19-ide
from Andre Hendrick, the system became hung. The server was
responsive to ping but ssh and http service stopped working until
we rebooted. The hang did not happen instantly, but took several
days of uptime before the system hung. Looking through the logs
we noticed that "stuck on TLB IPI wait (CPU#0) was logged 128 times
in one second. Also during that second, 4443 packets were rejected
by the kernel coming in on eth0, of which 2681 were aimed at port
137. These packets came from 60 addresses not on our local network
(packets destined to 137 on our local network are rejected, but not
logged). Of other note was this kernel message: "dst cache overflow"
"last message repeated 9 times". Since this did not crash the
machine, there is no oops output. We were running the mon package
from 3 other servers during this time and noticed shortly after
the hang that several services were failing (ssh, http, etc). Even
ping failed a few times.
