The behavior was recognized as a software issue with ID POA-115023.

Resolution

Collect debug information for further analysis by following steps:

  1. Login to OA core node and get PID of Java process. For example:

    [root@poa ~]# jps
    31811 Jps
    667 jboss-modules.jar
    
  2. Execute kill -3 667.

  3. Save copy of /var/log/pa/console.log from Core node. (it could be required to perform deeper analysis).

  4. Restart pa-agent and pau services on Odin Automation core node as described in the article.
