Bug in valheim-server script

[thetaiter]

I got a bunch of lines like this when my server when down for restart, and the server did not come back up.

Do you have the complete log? From start to error.

[thetaiter]

What is the best way to do that? Supervisord splits the logs into stderr and stdout, so it is difficult to reconstruct the logs back in time order.

[thetaiter]

If this helps, it is happening during the nightly restart every night. Shutdown works successfully, but the server is never restarted.

Here are the relevant env variables I have set:

  DISCORD_WEBHOOK: <redacted>
  PRE_RESTART_HOOK: 'curl -sfSL -X POST -H "Content-Type: application/json" -d "{\"username\":\"Odin\",\"content\":\"Restarting server $SERVER_NAME in one minute!\"}" "$DISCORD_WEBHOOK" && sleep 60'
  VALHEIM_LOG_FILTER_CONTAINS_Spawned: "Got character ZDOID from"
  VALHEIM_LOG_FILTER_CONTAINS: 'Unity Log'
  ON_VALHEIM_LOG_FILTER_CONTAINS_Spawned: '{ read l; l=${l//*ZDOID from /}; l=${l// :*/}; msg="Player **$l** joined server **$SERVER_NAME**\nIP: **$(curl ipinfo.io/ip):$SERVER_PORT**"; curl -sfSL -X POST -H "Content-Type: application/json" -d "{\"username\":\"Odin\",\"content\":\"$msg\"}" "$DISCORD_WEBHOOK"; }'
  PRE_BOOTSTRAP_HOOK: 'curl -sfSL -X POST -H "Content-Type: application/json" -d "{\"username\":\"Odin\",\"content\":\"Starting server $SERVER_NAME.\nIP: **$(curl ipinfo.io/ip):$SERVER_PORT**\nThe server may take ~5 minutes to start up before you can connect.\"}" "$DISCORD_WEBHOOK"'
  SERVER_PUBLIC: true
  UPDATE_INTERVAL: 10800 # every 3 hours
  UPDATE_IF_IDLE: true
  RESTART_IF_IDLE: true

[thetaiter]

Also, the PRE_RESTART_HOOK does not fire.

Just attach two files? My guess is that the container doesn't have enough resources. See https://github.com/lloesche/valheim-server-docker#system-requirements

[thetaiter]

Bingo, that was it. Didn't have enough RAM allocated. Thanks!
