[Variable™]

This has nothing to do with crashdetect. If you are using a downloaded script, make sure it has no backdoors that others might be aware of. Anything that can give that player the privilege to stop the server should be commented/removed from the script.

The server shows 'online' in the panel because the task is working, but the server isn't. That's why you have to restart it to get it working again.

Edit: You should censor the IPs though.
