500 Threads spawned on PegaRULES on Pega 8.4.1

Hi ,

We see our environment performance declines. As a result of subsequent analysis of the problem, a marked increase in Java threads is observed within the JVM.

Upon looking at the thread dump we see the following pattern, can you tell me why is it going into parking to wait for 1 particular object (<0x00000005dd0001c0> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject)) for around ~520 events
