Very recently, a web application ( JSP / Iplanet6 / Solaris 2.8) has begun to
freeze up. Web server logs indicate:
Internal error: Unexpected error condition thrown
java.lang.OutOfMemoryError,no description), stack: java.lang.OutOfMemoryError
This happens intermittently, with no obvious cause, and it just started
happening this morning (no changes have been made to either the server or the
application). It resolves itself and the application resumes just fine. But
it's irritating for pages to freeze up on people.
I *suspect* another application is using too much memory, but can't figure
out if that is the case.
Raising the JVM heap (in server admin GUI) to 256 didn't help. We can't /
don't want to raise it any higher and don't think we should need to -- we
want to find the root cause of this problem, since it hasn't happened before.
Can anyone tell me:
1. Do applications share the JVM? If so, can we turn that off?
2. How best to isolate the root cause of the problem? By the time we see the
error in the web server logs, ps -efl shows no processes eating a ton of
memory and the app has already fixed itself.
Any insights appreciated.
