  5. Following error could be found in core.log:

    180303 23:03:13 INFO  [org.apache.http.impl.client.DefaultHttpClient] (EE-ManagedExecutorService-sync-resource-usage-Thread-13) I/O exception (java.net.NoRouteToHostException) caught when connecting to {s}->https://192.168.1.54:443: No route to host (Host unreachable)
    

    Where 192.168.1.54 is IP address of Endpoint Host for corresponding application instance.

Cause

All Java threads were occupied by Synchronize resource usage and were not released since the task was not completed successfully. The task remains in running state despite of raised exception.

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.
