Re: thread hang on execute call

hi
i sending procedure as attachments that is called by java program.
please  get it from attachments.
i creates 15 worker threads and there is queue for job.
worker threads get job from queue if it there and do some db operation.
and wait if there is no job in queue. there is another thread that push
job in queue.
since whole processing takes time.....so worker threads always find job
in queue.
so they run nonstop and make db call to this procedure.
after around 2 days all threads get stuck one bye one.
then there is no response from either side.
worker thread also do some memory intensive operation  at their side.
it could be that threads are running low on memory so then might not be
able to respond postgres process. but jvm doesn't show out of memory.
and both end are waiting on recv call.
please tell me if you need more info or the way i should try to help you
people to diagnose problem.

Following two line or from logs

LOG:  unexpected EOF on client connection
LOG:  could not receive data from client: Connection reset by peer

well i am not sure when this loggin happened. either after when i killed
java process or before it.

thanks a lot  for your nice help.
