I’ve been investigating the issue where one of services in our snap does not recover after being killed by watchdog.
err systemd snap.ping.service: Watchdog timeout (limit 15min)! notice systemd snap.ping.service: Main process exited, code=killed, status=6/ABRT notice systemd snap..ping.service: Unit entered failed state. warning systemd snap.ping.service: Failed with result 'signal'.
This is the code in the snapcraft.yaml:
ping: command: usr/bin/ping-service.sh daemon: simple restart-condition: always restart-delay: 60s watchdog-timeout: 15m
What are the preconditions for it to enter failed state? How can we make sure it always restarts?
