We are unable to start the agent machine and we dont see the status file in the agent directory .
When we try to stop and start the agent it says Agent is already running with pid 0.
Release : 11.4
Component : Workload Automation System Agent
The agent was improperly terminated as part of a system reboot, this leaving behind the .lock file. This was preventing agent from being started.
After removal of .lock file, the agent was able to start without further issues.
