Java fails to start or create thread unexpectedly when launched through xinetd

Issue

• We launch multiple JVMs through xinetd. When multiple JVMs are running, additional JVMs fail to launch, crashing during start due to java.lang.OutOfMemoryError "Cannot create GC thread. Out of system resources"
• Our JVm starts throwing java java.lang.OutOfMemoryError "unable to create new native thread" errors. We increase our process ulimit, but it seems to have no impact to allow more threads.
