Message WorkWrapper caught exception: 

When I checked the opmnctl status , I can see the OBI Server is down.

Reason:

 When opmnctl is up and running and any of the services is failing. Then this is an issue with

1.  Configuration files like instanceconfig, NQSConfig  
2.  Check the RPD once. Might be an issue with RPD credentials

Solution:

1.  Try restarting the particular services in command line  like opmnctl startproc ias-component=coreappliaton_obis1 
2.  If the above step doesn't help check the log files and double-check your configuration files
3.  If this is an issue with RPD, Try re-deploying the RPD from the em url. And Restart all services.

After this, your OBI should be up & kicking now......
