[SOLVED] NPM - PM2 application disappears/uninstalling alone randomly

Issue

I have a Debian server running with Plesk. This server hosts the pedagogical platform I created. This platform uses WebSocket technology to allow teachers and students interactions in real time.

From the side server, a nodejs script started by PM2 manages all this.

My problem is that in a totally random way and without anyone doing anything, PM2 "uninstall" alone and the WebSocket server stops working ...

I can solve the problem easily using: NPM Install -G PM2 and restart the script.

The hours are never the same and do not match with a cron task:

• First time early December in the morning
• Wednesday, December 22 in the morning

(I then create a monitoring with Uptime Robot)

• Thursday January 13 at 5:12 am (GMT+1)
• Wednesday, January 26 at 15:57 pm (GMT+1)

I can't find anything in log files ...

It's really problematic because we have many users and a continuity of service to ensure.

Any ideas ?

Thank you

Solution

The problem seems to be caused by Plesk which deletes the elements installed globally in /opt/plesk/node/17/bin I changed approach. I installed PM2 locally in an other folder. Problem solved.
