Looks like something to do with fa-mlat-client. Other feeders and obj’s MLAT still running.
piaware.out after restarting the client with “sudo service piaware start” 20 minutes after service stopped:

Slightly at a loss about how that error could possibly happen…
What do you mean by “service stopped”? Was piaware still running but not doing anything? Or had the piaware process exited?
What time did you restart it?
Is there anything in dmesg output that looks suspicious? (e.g. out-of-memory killer)
