Hello,
We have a group of web and mail servers that run under a moderate
load. We recently upgraded them from 4/5.x to 6.0. While we
thought we had done enough testing, apparently we hadn't and are now
experiencing panic's on a number of the servers. Some of our more
heavily loaded servers have been fine for days, while others will
crash every 6 to 36 hours. Below are some pieces of information
that may be helpful.
Should I be posting this to another list as well?
I know I can decrease NMBCLUSTERS dramatically, and give more memory
to the kernel if that would help.
I've read a number of similar cases where this panic was related to
a hardware failure, and while I can't rule that out completely, it
does seem unusual that several servers are apparently having the
same problem. Could it be that hardware problems existed before the
upgrade, but are now brought out by the increased load caused by the
new OS version and other installed software? We have IPMI cards in
some of the crashing servers and they all report normal
temperatures, fan speeds, and voltages. Nothing unusual in the event logs.
I'm willing to dig deeper and do more testing if anyone has suggestions.
As suggested, we have upgraded to 6.1-RC2 and are experiencing the
same or a very similar panic. Some things have changed on the
system, so I'll re-post our config, backtrace and dmesg again.
Also, in the past I have seen kgdb report the process that caused the
panic, as well as some other information when first loaded, but
sometimes it doesn't show that information - am I doing something
wrong there? It has shown that information before, and it has always
been tcpserver from the ucspi-tcp-0.88_2 port.
