Background Tasks just keep building up.

[kyleroarke]

We have an issue where background tasks just keep piling up. The processing speed of these background tasks seems very slow and workers seem to get stuck very often leading to this condition. Rebooting only resolves temporarily. We are stuck and really don't know why this condition occurs. When the tasks pile up, inventory becomes increasingly inaccurate. We are running 0.17.10. Any ideas on how to troubleshoot why this happens?

I'll add that this is running in docker and CPU never goes higher than 30% on the machine. Memory is good. It just seems like when tasks build up, the program just gives up and lets them keep piling up.

Currently processing these at about 1 task per second. But that is nowhere near fast enough.

Do you have the cache server running in your setup?

If this is not running then the background worker is limited to a single worker thread - https://docs.inventree.org/en/stable/start/processes/#limitations

This will reduce the worker throughput significantly.
