URL: https://github.com/apache/pulsar-client-python/issues/153
We are using Python Pulsar producer clients in a web app that runs in UWSGI.
We have our settings set to terminate and relaunch workers after a certain
number of requests. We recently upgrade to Python 3.11 and the newest Pulsar
client (3.3.0). At that point we started to see segfaults as the worker process
was exiting. Here is the traceback that gets logged:
`!!! uWSGI process 85 got Segmentation Fault !!!

The resulting core files are filling up the server disks. We could ulimit
them but we'd prefer to avoid that.
