A couple of days ago, I have a RHEL ES 3.4 system that will stop
responding at different times of the day. Normally only twice a day that I
know of. It is running kernel-smp-2.4.21-27.0.4.EL and that last thing
that was in the log files before it stopped responding is the following:
# all of this is on one line in the /var/log/messages file
May 1 05:00:03 server3 kernel: .150 DST=xx.xx.xx.xx LEN=1420 TOS=0x08
PREC=0x00 TTL=64 ID=33408 DF PROTO=TCP SPT=3306 DPT=32887 WINDOW=5792
RES=0x00 ACK URGP=0
I replace the "DST=" with x's. It was the IP address of another system of
ours. All though, I am not sure what it was trying to do at that
time. This is the only entry before any of the reboots that looks like
this, so I am not sure if this is the problem anyway. I have just never
seen this before and believe that it is a cron job that I have running on
the other server to do a dump of the mysql database on this server. Thing
is that that job runs at midnight and only takes about 10 or 15 seconds to run.
Does anybody know if the kernel version that I am running has any
problems? I can go back to the 2.4.21-27.0.2.EL smp kernel if need be.
Thanks
Steve
