SIGSEGV 11 segmentation violation

[Subhash Nambiar]

Hi
Im getting core dump on weblogic server 5.1(part of it described below) .
It is not consistent but comes sometime and makes the server down.Can any body help me out with any clues for this abnormal behaviour.
Thanks in advance

This is a wild guess, as looking at a stack trace really doesn't tell anyone what the picture of the problem is. What is the program doing, what is the code look like, et al.
Is this an Oracle or a Weblogic problem?
If there is an insert happening or a large query. It could be that it can't extend that file. Meaning the size of the Cache Buffer size cannot be extended. Or the datafile can't be extended.
This is a question for your DBA, to check the file sizes and making sure it doesn't run out of space.
You can have your DBA watch as these programs run to see what is being sent to Oracle and how Oracle is handling it.
