Hey 👋
Just upgraded to Pro, I wanted to add more gunicorn workers to get more capacity (going from 8 -> 16), but the additional workers are unable to start.
Error message:
File "/usr/local/lib/python3.11/site-packages/sentry_sdk/worker.py", line 70, in start
self._thread.start()
File "/usr/local/lib/python3.11/site-packages/sentry_sdk/integrations/threading.py", line 56, in sentry_start
return old_start(self, *a, **kw)
^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/local/lib/python3.11/threading.py", line 964, in start

OpenBLAS blas_thread_init: pthread_create failed for thread 1 of 32: Resource temporarily unavailable
OpenBLAS blas_thread_init: RLIMIT_NPROC -1 current, -1 maxIt runs fine locally, any hint?
Thanks in advance !

Fixed by adding os.environ['OPENBLASNUMTHREADS'] = '1' on app start (from https://stackoverflow.com/a/57549064), not sure why it works 🤷
