Hello Lars! Thanks for your interest. The problem appears when all celery workers require 1Gb of RAM each in idle state. They hold this memory constantly and when they do something useful, they grab more memory. I think 8Gb+ in idle state is quite a lot for my app.
> Did it crash your system or prevent other processes from having enough memory? yes. More over, sometimes corporate watchdog just kills my app -- https://mail.python.org/mailman/listinfo/python-list
