found dead multi-threaded server

Hi Gurus,

We have recently upgraded our DBs from old 7.3.2 version to 8.1.6.0 and have moved from dedicated to MTS.

since then we are getting ORA-600s in alert.log of all the DBs with various first arguments some of which I'll list here : 15429, 15439, 16365, 16375, 17034, 17182, 17280, 17281, 17285, kohlnm120, kohcpi298 etc. These are the most frequent ones. Though the DBs are up and running these errors are being consistently logged in alert.

None of the instances have crashed ever since we have upgraded.

I've opened up a TAR on metalink and have been told that 8.1.6.3 patchset is to be applied.

Now what I want to know is if others have also encountered these errors and if applying this patchset has solved the problems. If not then what are the other things to be done (I mean does moving to 8.1.7.3 will necessarily solve the problem ? We are reluctant as this will mean another period of downtime for the users...)

Also what is the source of these errors ? Will moving into dedicated arch solve our problems ?

(I somehow tend to trust this list more than Metalink !!)

TIA,
