Hey @Andrey_Sudnik
This error comes from Bull, the library we use to handle the queue.
There is an explanation about Stalled jobs that can be found here: Welcome to Bull’s Guide | Premium Queue package for handling distributed jobs and messages in NodeJS..
This may come from 2 possible reasons:

I would suggest checking your worker’s health and perhaps increasing the count.
