Milter-greylist

I think you two may have stumbled onto our problem as well:

We have a cluster of 5 incoming servers, all using milter-greylist.  I
have a script run out of cron I was using to check milter-greylist's
status to restart automagically after a crash.

A random lsof spot-check shows the following:

root@xxxx:~# lsof | grep milter-gr | wc
    924    7876   94006


so based on this:


root@xxxx:~# ulimit -a
core file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 1024
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 7168
virtual memory        (kbytes, -v) unlimited


I guess we're not crashing until we hit 1024?  Which seems to happen
somewhat frequently.

I'll try setting the ulimit open files to 2048 and see how things go.

for what it's worth, I don't think they're leaking, as the count tends
to fluxuate up and down quite a bit.  I'm also thinking that it's partly
our fault for giving sendmail's milter setup a much longer timeout.
(trying to work around possible DNS latency with libspf support, etc.)

Cheers,
