Description:
I am struggling with a bug on my production server using Horizon.
ErrorException: Warning: PDO::prepare(): MySQL server has gone away [internal] in unserialize
You can see a stack trace of the error here: https://sentry.io/share/issue/b105b7946b524a9e841f56f44445ea14/
As far as I can tell, this error should be caught by the Laravel framework. I'm not sure why it's not being caught and turned into a QueryException which would then trigger the reconnection and/or killing the worker.
My understanding is that any Exception should be caught and then re-thrown as a QueryException, which would then be properly caught by the framework and then reconnected to the database.
This is an occasional error so it's difficult to reproduce; I've tried to manually throw a similar error but it is caught properly and handled properly.
Any general guidance on why this error might be different in production and ideas on how I can isolate the error would be appreciated.
