Were are battling this even as I type...
It seem that if jBoss hits the operating systems pid (thread) limit for a
process, it throws out of memory exceptions. We just ran some load test
scripts and when we get too many threads, pop goes the weasil.
I'm looking at two possibilities... Catch the out of memory exceptions in
my code and then sleep for a bit and try again (not a great olution) or
throw more hardware / operating system at it.
Maybe both.
Does anyone know what jBoss should do when the thread limit is hit?
Thanks...
Jim

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I -
I took the one less traveled by,
And that has made all the difference.
