Hi,

HIFX-48716 is provided to fix an issue where Process Commander Requestors significantly slow/become unusable after repeated calls to Hazelcast.  The following thread dump is repeatedly thrown after this issue begins to occur:

 

"https-openssl-nio-443-exec-9" Id=208 in WAITING BlockedCount : 0, BlockedTime : -1, WaitedCount : 63, WaitedTime : -1     at sun.misc.Unsafe.park(Native Method)     at java.util.concurrent.locks.LockSupport.park(Unknown Source)     at com.hazelcast.spi.impl.AbstractInvocationFuture.get(AbstractInvocationFuture.java:153)     at com.hazelcast.spi.impl.AbstractInvocationFuture.join(AbstractInvocationFuture.java:136)     at com.hazelcast.concurrent.lock.LockProxySupport.lock(LockProxySupport.java:84)     at com.hazelcast.concurrent.lock.LockProxySupport.lock(LockProxySupport.java:76)     at com.hazelcast.map.impl.proxy.MapProxyImpl.lock(MapProxyImpl.java:262)     at com.pega.pegarules.cluster.internal.PRHazelcastDistributedMapImpl.lock(PRHazelcastDistributedMapImpl.java:385)     at com.pega.pegarules.data.internal.lock.LockUtils.waitTillLockIsAvailableOnPrSysLocksTableInDistributedMap(LockUtils.java:105)
