We are using the proofpoint rules and all OPNsense versions from 25.1 to 24.x are affected. Error message is:
<Error> -- Just ran out of space in the queue. Fatal Error. Exiting. Please file a bug report on this
It looks like a broken rule update is responsible for this, since ample memory and disk space is available on our boxes.
One more observation: Only boxes with one of the three Aho-Corasick Pattern matchers are affected, even with today's updated rules. Boxes with Hyperscan matcher were not affected. After changing the matcher to Hyperscan, the problem was solved on all of our previously affected firewalls.
I hope this helps identifying and fixing the cause.
Ours started erroring out on the 20th, same symptoms, and same temporary resolution - Hyperscan.
Same here
