RAC Failing after O/S patch

William Wagman



I am running a 2 node RAC cluster on Oracle Standard Edition,
database is on ASM and CRS is also. The O/S is RHEL3. Last
week we upgraded from 2.4.21-32.0.1.Elsmp to 2.4.21-47.0.1.Elsmp and now
in one of the two instances am seeing the following errors in the
database instance (not the ASM instance) alert log and the trace files
being generated...

The errors are only appearing on node 1. I have searched Metalink and
the web and found references to these errors but nothing which matches
this situation. I am still waiting to hear from the sysadmin as to
whether or not he has seen any reports of the O/S encountering memory

I would appreciate any thoughts as to what to look at or suggestions as
to how to track down the error. So far Oracle has been unresponsive.
