Description

The following process seems to grow in an unconstrained fashion:

/usr/sbin/tcpdump -s 256 -v -S -l -n -e -ttt -i pflog0

Observed over the past 6 months of running 2.1 snapshots. Currently running Feb 4th 2013 snapshot. See attached RRD graphs for evidence.

This seems to be associated with option "10) Filter Logs" in the console menu and function filter_pflog_start. It is started on boot and every time the filter reloads, so I assume it has to do with logging.

Of course users with embedded systems will be more sensitive to this, as noted in these forum posts:
