Environment

Resolution

Intilaly we stopped the WCC services

Renamed the CA-wcc.log

Restarted the WCC services

We could see that the CA-wcc.log was stuck after initializing httpinvoker

We stopped the WCC services again and searched for any hung java processes.

We stopped csampmux process in task manager

This time when we restarted the WCC services we could see that there was an error

We checked and found that the application server was hung

After retarting the application server services

Now the WCC is up and we can check the job statuses
