Hello all!

Since few months I'm getting the following typical output from ac -p
(and hence monthly run output):

-- End of monthly output --

Note that 15572 / 30 / 24 = ~21 terminals.
I'm using xterm's in xorg, but not in that quantity
(normally 2-3 and not 24/7).
Is this normal/expected?
In any case it is different from behaviour of previous FreeBSD releases,
which can disturb sysadmins.
