Description

We are seeing ClasscastException while evaluating kie rules. Everytime we see this issue we have to restart the server to fix it.

This doens't happen to all our kubernetes pods where same kie-server is running. This happens to either 1 or 2 pods all the time.

This issue is also not reproducible

Also we see different stack Trace with ClassCastException every time, Here I am pasting some of them:
ERROR 1 :
[className=DroolsKieContainerCommandServiceImpl]- Error calling container 'kie_personalization'java.lang.ClassCastException: null

ERROR 2:
Error calling container 'kie_personalization'java.lang.ClassCastException: org.drools.core.reteoo.RuleTerminalNode cannot be cast to org.drools.core.reteoo.LeftInputAdapterNode
