--- Comment #8 from noah.bergbauer@tum.de ---
The workaround I'm using now is:

echo "set timeout interval 2" | pfctl -mf - && echo "set timeout interval 1=
" |
pfctl -mf -

Every hour in crontab.

It causes the purge thread to wake up
(https://github.com/freebsd/freebsd/blob/e0bfaddbc2f6dac2c494ca1fa0566cd4e2=
ee0659/sys/netpfil/pf/pf_ioctl.c#L1924)
and from there it works fine for a while (very random, last time it was jus=
t a
few seconds but now it's 20 minutes and still going).


So this means that it's apparently just not waking up for some reason.
