Celery worker stuck with 100% CPU


#1

In our redash setup we have a problem that our celery worker gets stuck at 100% CPU and then fully occupies a core.
This goes on until all our cores are used up and redash crashes.

Initially we though it was related to the celery bug https://github.com/celery/celery/issues/1845 however we are facing it in the latest redash version with a higher celery version.
One point to note is that strace gets stuck when we run it on the process and shows no output.

Please let us know how we can get the reason for this behavior.
Thanks for your help

Maybe it’s related to this?

Oh, wait. Did it start before v6?


#4

Yes
It started before V6 and still is there
Initially we thought it was celery issue but even after upgrade its still the same.

Any pointers would be appreciated.
