java.lang.OutOfMemoryError

Hi again,

I 've build a UAS generating programm ,using the example at
\jain-sip-1.2\src\examples\reinvite.I create several UAS ,about 200 .These UAS
expect an INVITE ,respond to it ,and then receive an ACK request.A dialog is
never created ,i just want to simulate the message flow.Each UAS receives
these messages about every minute.When i try to run the program for an 20-30
minutes i start to get a java.lang.OutOfMemoryError finaly i got a:

Error message is null

Caused by: java.lang.OutOfMemoryError


and the program stoped.

These are the parameters i used for the program:

pr.setProperty("javax.sip.IP_ADDRESS", uac_host);
		pr.setProperty("javax.sip.STACK_NAME", "sip_uac");
		// Set TRACE_LEVEL to 0 in your production code for max speed.
		// Set TRACE_LEVEL to 16 for logging tracesm, and 32 for debug + traces.
		pr.setProperty("gov.nist.javax.sip.TRACE_LEVEL", "0");
		pr.setProperty("gov.nist.javax.sip.SERVER_LOG", "log_uac.txt");
		pr.setProperty("gov.nist.javax.sip.THREADPOOL_SIZE", "infinite");
		pr.setProperty("gov.nist.javax.sip.CACHE_CLIENT_CONNECTIONS", "false");

I tryed not to set the THREADPOOL_SIZE" and the CACHE_CLIENT_CONNECTIONS
parameters and i still got the same results.Is there a reason why these is
happening.I use a similar programm to create the UACs that send the
requests.After qa UAC  sends the  ACK request ,it dies ,-both UACS and UASs
are runnable and run in their one threads-,in the next minute more UAcs are
created and so on.The only difference is that the UAS dont die ,but they keep
receiving requests,well untill the memory runs out.
Could you tell the reason this is happening ,and if there is a solution to
this problem.


Thank you MIchael.
