(-92) Checkpoint connection error: 200 - The request either made it through the OP-tunnel to the checkpoint but something went wrong there, or it got stuck on the ASM tunnel endpoint (the other side than OPMS machine).
(-94) Checkpoint timed out - This indicates that the OPMS received the request, but no response from the monitor checker was received.
(-95) Checkpoint Error: 503 Service Unavailable. Aborting execution because giveup time has passed - This request has made it through the tunnel to the OPMS machine but the checker (agent) did not pick the requested job up. This can happen if the machine is flooded with checks - the agent is busy executing one check and it has no time to pick another one.
