ISPN000136: Error executing command PutMapCommand on Cache 'c2oear-snapshot.ear.web-snapshot.war', writing keys [omitted]: java.lang.ClassCastException: org.infinispan.container.entries.NullCacheEntry cannot be cast to org.infinispan.container.entries.MVCCEntry

Environment

PAM 4.4 

Clustered PAM environment

Cause

The port needed by PAM is being used by another application

Resolution

1. Check the Ports Used by PAM

2. Stop PAM services and ensure the ports from step 1 are available. 

Note: You can use the netstat command in Windows OS. ie: netstat -ano | findstr "port number"

3. Start the PAM Services once all the port numbers are available.
