Date: 5 Apr 2002 07:42:51 -0000 [thread overview]
Message-ID: <20020405074251.22007.qmail@mailweb12.rediffmail.com> (raw)
Hello all,
we are running clearcase,sun grid engine on RedHat Linux 7.1
(kernel 2.4.2) on IBM Xseries one U servers that has
two CPU's and we mount all the files to be processed using
autofs.
Here is uname -a
Linux 2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686
unknown
I have more then sufficient physical memory and swap space
Here is some swap space detail form top
Mem: 1543868K av, 507684K used, 1036184K free, 0K shrd, 317576K
buff Swap: 5116576K av,0K used, 5116576K free 33076K cached
we are running n number of IBM X Series server every now and then
one or two servers crashes and don't allow me to do anything
except hard reset.
The /var/log/messages says something like:
