It looks like the "celery worker" process is maxing out both CPUs on our MHN server. I haven't the first clue as to why and would appreciate assistance in figuring it out. I'd like to stay in the good graces of my virtualization team.

Gracias!

The celery worker does 2 things

1. Handles password resets

2. Downloads signature files from emerging threats and stores them in MHNs DB

If you don't care about these you can disable it by calling

sudo supervisorctl stop mhn-celery-worker

Thanks, Jason!

Unfortunately even with mhn-celery-worker stopped, I'm still seeing 100% CPU usage.

You can ignore my previous message. Apparently I just wasn't patient enough in waiting for the existing process to die. Looks good now.

Thanks!

I am having this same issue but would like to keep this process online for the signature updates. Is there anything I can provide to assist with troubleshooting this further?

Sorry to dig out this old post, but this is still an issue for us. We're now at a point where downloading sigs from ET is something we're going to want to do.

What can I do to further troubleshoot why mhn-celery-worker constantly sits at 100% CPU usage?
