So it is telling you since it started the GC (Garbage Collection) has run 381 times

In an hour do it again. Subtract it out and you know how often the GC is running.

Also your heap is set at 50M. Good enough but since it gets up to 247M kinda quick, I would set your initial up to 275M or so. I would also change the maximum to about 1G or at least 740M. (you have plenty of memory on your system if I remember correctly). Then watch it. That should solve your problem. Since 5G seems to be where IBM wants to run the 64bit JVM instead of the 32bit JVM your still way under the limit for a 32bit JVM......

Forgot to change the jobnumber and ran it and I got:
JVAB612-Job contains a JVM which is not supported by this command.

Ok, my bad.

So I changed the job number and reran it. I still get that message.
Recovery . . . : Use the GENJVMDMP, PRTJVMJOB, and WRKJVMJOB commands
instead of this command.

Joblog says
Server starting with user profile QEJBSVR and JDK 1.6.0.

Picked the first off of the list, GENJVMDMP. Ran "successfully". However,
where is the output? The help on the command doesn't clue me in.
Something also tells me I should have changed the default from TYPE(*JAVA)
to TYPE(*HEAP) but if I can't find the output first, who cares?

So I ran PRTJVMJOB JOB(864283/QEJBSVR/AS70SVR) OPTION(*ALL)
That generates 631 pages of stuff. Around page 8:
