It happening for me with billiyard only , i have tried running it from the command line with or with out using celery ,

File "/venv7/lib/python3.7/site-packages/billiard/pool.py", line 1399, in starmap starmapstar, chunksize).get() File "/venv7/lib/python3.7/site-packages/billiard/pool.py", line 1791, in get raise self._value.exception File "/venv7/lib/python3.7/site-packages/billiard/pool.py", line 1267, in mark_as_worker_lost human_status(exitcode)), billiard.exceptions.WorkerLostError: Worker exited prematurely: signal 9 (SIGKILL).

i am using celery latest version 4.4.7 and billiard 3.6.3.0 and kombu 5.0.1

When i was trying to run the multiprocessing pool job in celery it wasnt not allowing to run it , so i shifted billiard pool for parallel processing

i was trying to run about from command line with 32 parallel jobs using billiard i got this error and if shift back to multiprocessing i am not getting this error.

Stuck with this problem in celery , please suggest me if i need to change any default settings

Hi @veerendrapolepalli, @h0rn3t! Have any of you guys found a solution to this problem? I'm having the same error, using Celery current last version celery[auth,redis,tblib]==5.2.6 and billiard==3.6.4.0.

I am experiencing the same problem, some PDFs cannot be processed by ocr (celery)

tl;dr increasing the machines memory fixed the issue for me 👍 there is also a possible solution to deactivate searching for barcodes if u are short on memory - with environment variable PAPERLESS_CONSUMER_ENABLE_ASN_BARCODE=false

Hi @auvipy, thank you for the fast reply. I tried to figure it out, but couldnt find the celery service file for configuration. Randomly I saw my machine was eating all the memory at once so I increased it, now it works flawless.

Have a great day :)
