We have CENTOS 5.5 on DELL server and several ORACLE databases on version 10.2.0.4 and 11.1.0.7.

You might check with Oracle, and see if it's a know bug. mark

Can be an application bug or pretty near anything else (segfault is essentially memory corruption, but most commonly due to code bugs). Turn to application level logs after ruling out hardware (which you seem to have done). /Peter -------------- next part -------------- A non-text attachment was scrubbed...

If that doesn't fix it, call Oracle support. -Ross
