--- Comment #2 from Aiko Barz <aiko@torrentkino.de> ---
Today the other Bridge-Server had this issue.
But I forget to collect the memory situation before applying the workaround=
. :(

My current workaround:
$ ifconfig ix0 down
$ ifconfig ix0 up
$ ifconfig ix1 down
$ ifconfig ix1 up

This is the memory situation after applying the workaround:

$ sysctl hw | egrep 'hw.(phys|user|real)'
hw.physmem: 17095405568
hw.usermem: 14351601664
hw.realmem: 17179869184

$ grep memory /var/run/dmesg.boot
real memory  =3D 17179869184 (16384 MB)
avail memory =3D 16531873792 (15766 MB)

$ freecolor -m -o

Those machines only run PF. Nothing else.
