When a machine is unavailable, an Autosys job submitted to that machine will go to the pending machine status (PEND_MACH).
This interrupted job will be started, once the machine comes back online.
This error can happen when a job is sent to the machine successfully, but an acknowledgement is not received from the Agent in a timely manner.
When the Agent does not immediately acknowledge the job start event, the CA WA AE Scheduler will raise the AUTO_PING alarm with COMM_ERR_14 message to alert of a potential manual intervention, that may be required for the job.
If RUNNING and SUCCESS statuses are later received for the job, the alarm can be ignored and no manual intervention is required.
