MTS server process seems to die and resume at random

Folks,
I'm running my oracle 8.1.6 STD on solaris8, sun4u. Lately I have been getting this ora-600 which seems to get cause by the crusade of my MTS. I couldn't find the crusader :P Here is a log that got generated by the alert log

The process seems to have resumed after that dump. But have no clue on what is causing this.

For your reference, here is some stuff from my trace file

Dumping MTS state at level 10
Global: Svc Name=active, Max Svrs=20, Max Disp=5, Max Ses=110

     Svrs: #act=1, #sta=49, #trm=75, #unt=26, #max=9
     Starting: flg=20, current=1, index=7

In this dump I could notice that there were around six server porcess that were free at the time of dump. So, this had puzzled me further on finding out what was causing the problem.

On this instance,I use the php to open persistent connection to the database one user. But under that user profile, I have also setted the idle time to be max of 5min. So would this connection be disconnected, if the session was idle for 5min or would it be ignored? Could this be a cause for this problem?

Is there any tracking that I could do on this to see what is causing the problem? Since this problem seems to be random, does not know what could be the causing it, I have no clue on what the steps/measures to take to troubleshoot it.

Some help/thoughts would really be appreciated.

Thanx for your time and thoughts,
Sambavan
