WAS6.0.2.  SuSE Linux Enterprise Server v9 sp 2.

WAS6 unexpectedly just unloads.  No errors reported in JVM logs.  Happens
about every 10 days or so.  OS says it has been running 19 days.

Ideas of what to check, where to look?

Thanks,
Jim

Might be something in the WAS logs. If not, you might check to see if
there's a javacore* file in one of the WAS directories. There's usually
a javacore if WAS has a bad problem.

Thanks.  That does look like the right direction.
Am I right, the problem appears to be with libjitc.so???  Or do I need to
look further in the dump?

Here is a snippet:

That's what it looks like to me. Make sure you have all the relevant
fixes applied, and I'd still open a PMR with IBM.

We have updated to fixpack 6.0.2.1.  We was at 6.0.2.0.  Now we will have to
wait and see.

On a side note, we are looking at DB2 running on the same Linux box - and
that seems to be an interesting adventure in itself.
