                at com.pega.pegarules.session.internal.mgmt.PREnvironment.getThreadAndInitialize(PREnvironment.java:384)


Steps to Reproduce



Restart the cluster.


Root Cause



A defect in Pegasystems’ code or rules. Stale node information exists in the cluster node cache due to an improper shutdown. As the cache is now in an inconsistent state, it does not allow the node to start up.

Resolution



This issue is addressed in Pega 7.2.1.
