HELP: Oops

[Satya Prasad DV]

hi,
  We are using the RHL 7.1(kernel 2.4.2-2  source custom built to include aic7xxx  SCSI adapter in built support )  with cvs software version cvs-1.11.1p1 patched to get additional info for logging using AlternateInfo=yes in config. We had no trouble with this s/w for over one year. Recently we upgraded the server by increasing RAM to 512M and adding scsi drive for the cvs repository partition.

After this, the server started spewing out lots of Oops messages after 7-8 days of operation. If I reboot the machine the problem disappears for a while and starts again.The oops seems to be coming when the cvs process is running. Iam listing the ksymoops output below.

I ran memtestx86 but it does not report any problems with the new RAM.

Kindly help me to locate the problem.

Thanks in advance,
