What does a task group status of 'Lost' mean?

What does this status indicate? I’m running a long running batch task inside a task group, which is indicated as being lost, what does this status mean please?

Hi @robsonj, “lost” indicates the Nomad Servers are not able to make contact with the Nomad Client that is running the marked allocation. Since the servers do not know what the status of the Client or any of it’s allocations are, they are marked lost. You can control the behavior from that point by setting stop_after_client_disconnect or max_client_disconnect

Got it, thanks Seth. They eventually returned to a running state, so guessing the client got a bit overwhelmed for a short period, possibly temporarily starved of CPU while our jobs were starting up
