This happens about once every two weeks, and when it does, it fills up the system log.  I can't figure out which docker is misbehaving.  I stopped all dockers and even disabled the docker server, then restarted nginx using "/etc/rc.d/rc.nginx reload".  No affect, still scrolls.  The RAM usage is only 60% so it's not actually out of memory I don't think.

 

Diagnostics attached.

I've also been seeing this error a lot with the last two point releases of 6.11. Anyone got any ideas?

Same. I don't think you'll get much response here. I'm going to post this in the NPM forum but there's not a lot of action there either.

 

 

I don't remember what fixed this, sorry.  I think it had to do with Nextcloud though.
