Worker VM Out of Memory

There are a number of reasons why a worker VM could be out of memory.

• One of the Engines could have a memory leak.
• The Celery service might be running in DEBUG mode.
• There are other reasons.

First, check to see if the Celery service is running in DEBUG mode. If you are running Celery on the command line, it is the -l flag. If you are running Celery as a service, look in /etc/default/celeryd for the CELERYD_LOG_LEVEL parameter. In production, it should be INFO. If you change the logging level, restart the Celery service.

If Celery is not the problem, just reboot that worker VM.
