I'm experiencing the same problem with spamc hanging on my mail server:
bash-2.05b# ps aux | grep spamc
qscand 23346 0.0 0.0 1904 4 ? S 19:40 0:00 /usr/bin/spamc
-c -f -d 192.168.1.23 -u

bash-2.05b# strace -f -p 23346
recv(3,
In the mean time a spamd child hangs on the spamd server:
bash-2.05a# ps aux | grep spamd
spamc 19519 104.1 2.7 22084 14128 ?? R 6:40PM 11:46.04 spamd
child
spamc 19507 0.0 1.8 19728 9608 ?? S 6:40PM 0:01.82 perl -T -w
/usr/bin/spamd -i
192.168.1.23 -A 192.168.1.18 -x -u spamc
spamc 19509 0.0 2.4 20676 12576 ?? S 6:40PM 0:00.82 spamd child
spamc 19510 0.0 2.3 20260 12132 ?? S 6:40PM 0:00.40 spamd child
Finally, spamc times out while spamd keeps eating CPU. This is the situation on
the spamd server:
bash-2.05a# lsof | grep 19519
perl 19519 spamc cwd VDIR 14,2 6528 2 /
(/dev/disk0s2)
perl 19519 spamc 0r VCHR 3,2 0t0 34932996 /dev/null
perl 19519 spamc 1w VCHR 3,2 0t1012094 34932996 /dev/null
perl 19519 spamc 2w VCHR 3,2 0t1012094 34932996 /dev/null
perl 19519 spamc 4r VREG 14,2 73087 377323 /
(/dev/disk0s2)
perl 19519 spamc 5w VREG 14,2 502932 377858 /
(/dev/disk0s2)
perl 19519 spamc 6u inet 0x02f85f4c 0t0 TCP
192.168.1.23:783 (LISTEN)
perl 19519 spamc 7u inet 0x02f874cc 0t0 TCP
192.168.1.23:783->192.168.1.18:
48499 (CLOSE_WAIT)
When all the spamd childs are blocked like this one my spamd server just stops
processing requests to
port 783.
I set up a cron every 30 minutes to run "kill `ps -aex | grep 'spamd child' |
grep '?? R' | grep -v 'grep' |
awk '{print $1}'`". This is a temporary solution of course.
