Thread Count and Out Of Memory Error

Question

Hi,
I was wondering if setting the ThreadPoolSize to a value which is too low can
cause an out of memory error. My thought is that when it is time for Weblogic
to begin garbage collection, if it does not get a thread fast enough it is possible
that memory would be used up before the garbage collection takes place.
I am asking this because I am trying to track down the cause of an out-of-memory
occurrence, while at the same time I believe I need to raise the ThreadPoolSize.
Thanks,
Mark

Oops ...
I was wondering if setting the ThreadPoolSize to a value which is too
low can cause an out of memory error.No, but the opposite can be true.
My thought is that when it is time for Weblogic
to begin garbage collection, if it does not get a thread fast enough it is
possible that memory would be used up before the garbage collection
takes place.Weblogic doesn't do GC ... that's the JVM and if it needs a thread it will
not be using one of Weblogic's execute threads.
> I am asking this because I am trying to track down the cause of an
out-of-memory occurrenceIt could be configuration (new vs. old heap for example), but it is probably
just data that you are holding on to or native stuff (e.g. type 2 JDBC
driver objects) that you aren't cleaning up correctly.
while at the same time I believe I need to raise the ThreadPoolSize.Wait until you fix the memory issue.
