Amavis decide_mail_destiny crash

  • 772

After upgrading to FreeBSD 12 I'm experiencing issues with amavis from time to time.

The reason for the crash in unclear for now.

A simple kill -9 $amavispid && service amavids start does the trick but after some hours everything starts over again.

This is the log output from the crash:

The last Lines continue till i kill the service, and spam the log file.

Again, after i restart the service everything is fine again. System resources are not exhausted. CPU Load is at 0.5, plenty of memory is left (~20%), disks are not filled up.

I have no idea where to search...

PS.: hostnames and domains are of course changed

EDIT: Just If someone else is facing this issue, I have found a workaround. You might just disable the Berkley Database feature that caches some results via $enable_db = 0; This is no solution, but a workaround!
