Ana,
Congrat. In our case it was some code running through dbms_job and some contribution from Oracle Discoverer. It was a dataware house application custom designed by Oracle Consulting..... Regards

Thanks Rafiq. It took me a long while to find out what the problem was. We have some consultants that monitor our databases and they have a daemon that runs constantly gathering information. This daemon was the culprit. We stopped it, and since then the ora 07445 went away, and we were able to resume our normal operations,

Ana

Ana,
I am trying to remember about this problem 2 years back with 7.3.4 and if I

am not wrong it was application related problem which was fixed by our developers at that time. It was my previous assignment so I cannot provide any further details. ORA-7445 is also like ORA-600 for catch all situation.....
I shall suggest to check application changes when this problem started and see notes for 8.0.6 upgrade whether it was fixed in that relaese.

Regards
Rafiq

I posted a question to the list last week regarding this error and didn't get any responses. I'm trying again. We're on Oracle 8.0.5.2.1, and Solaris 6.

A few days ago we started receiving ora-07445 errors in the alert log. This happened when had to reboot the server. If we shutdown/restart the database the errors went away. Starting Friday the errors are happening when shutting down/starting up the db. We shutdown the db at midnight and start it at 2:15 am every day. We get lots of core dumps and trace files filling up the file system. We clean up the files and start the db, after that we don't receive the errors anymore until next stop/start the db.

I have submitted a tar to Oracle support, but so far they haven't come up with a solution or a cause for this. We made the changes they suggested but it didn't help. Sun suggested some changes to the hardware, but it hasn't help either.

Can anyone out there provide some insights on this? Here is one of our trace files:
