Hi Jake,
While it's not a solution to the root cause of this problem (which seems to be
uncommon and hard to reproduce), changing the logrotate configuration to
"copytruncate" instead of restarting would probably make this go away.
That change is part of PF 4.1 by default now, as it seems better not to restart
services unnecessarily.
Regards,
