Now maybee you could succeed reloading your table with
the command: "pfctl -t ban -Tr -f /etc/ban", because this
command is more optimized and will allocate less kernel
memory. It will run faster too.
Hope that helps, and let us know if you find something with
"vmstat -m" output. If it is PF that leaks kernel memory, we
need to fix that!
Hi again, and thanks for responding earlier. Today is the first time I've
seen the problem happen again. This is probably due to several reboots
which have occurred since I originally reported the problem (some planned
and some unplanned).
During that time, I also updated to a snapshot, and then to 3.4-current
by source. I'm currently running 3.4-current from Feb 23.
pegasus:~$ sudo vi /etc/ban
pegasus:~$ sudo pfctl -t ban -Tr -f /etc/ban
pfctl: Cannot allocate memory.
Here's what vmstat -m says:

Here is the problem I think: 40MB of kernel memory for routing table
It might be PF table stuff..., not sure yet.
Do you reload your "ban" table very often?
Do you you have a big routing table, or IPSec table?
