Hi,

I'm trying to move from JDK1.5_17 to JDK1.6_11 on my application server(jboss).
In JDK5 everything went fine.
In JDK1.6 I’m getting "Out of swap space" error after ~ 14 hours.
It seems that in that particular point there is a GC and there is a big "jump" in the thread count, which probably cause for this error.
As i mentioned above, the problem was not reproducible in JDK5.
Does anyone knows what has been changed in JAVA6, or what should i do in order to solve this problem?
I'm using 64 bit machine and i tried to reduce the heap space but the problem is still reproducible.

Thanks in advanced,

Shay
