Hi Saad,I would also expect memory problems at the OS level. Did you check the Linux messages log (/var/log/messages)? You mention that the users were running pipelines - if the same box that runs the database also runs heavy user processes, it might have run out of memory which will activate the OOM-killer in the kernel. This will try and identify the least important process, which usually boils down to an oracle background process that does not seem to do a lot, and kill it in order to resolve the Out Of Memory situation. There will be a trace in the messages file of this.
The requirements in the installation doco should be used as a very minimal guideline only.. you must tune them to your situation.

I ran sysctl -A myself as root (thanks to sysadmin's short memory for not revoking my access), and then compared the results with kernel prerequisites for the installation. All the values are above the minimum settings required. So I think we can opt out this as a possible cause.I also ran the HCVE script as per metalink note Note 250262.1 <https://metalink.oracle.com/metalink/plsql/showdoc?db=NOT&id=250262.1&blackframe=1>No solution yet! :(On Thu, Apr 16, 2009 at 9:58 AM, Joey D'Antoni <jdanton1@xxxxxxxxx <mailto:jdanton1@xxxxxxxxx>> wrote:Could you have your sysadmin do a sysctl -A?

Can this be a bug? I'm just getting stumped. Can someone plz help me?

You should look for .trc files under the directory defined as "user_dump_dest" in you parameter files (cd ../udump from the directory where you alert file is located should take you to the right place).
