Environment
Resolution
A 'Lost Control' message means that the Agent can no longer find the Process ID (PID) of the spawned process that is running a job. This usually happens when the agent is restarted and the process exited while the agent was stopped.
When a job starts, the agent creates/updates an odb file in its "database" directory - this contains the job status. If the agent is stopped (or crashed), these files are checked when the agent restarts. This allows the agent to re-synchronize with the scheduler and send the correct status. By default, the agent does a warm start and makes this checking.
This agent behavior may be customized by modifying the agentparm.txt:
The oscomponent.noguardianprocess tells the agent to return the status of the jobs that were either active or inactive when the agent was recycled. Setting this parameter to false will not return this status. If the agent does a cold start (persistence.coldstart=true) then all the information in the base is deleted, no messages will be sent and oscomponent.noguardianprocess parameter is ignored.
