Hi!
I use cyrus 2.0.12 + pam_mysql, sendmail 8.11.0 on a dual p3/550 with 1G ram
(linux redhat7, kernel 2.4.2).
I've faced a very strange problem -- when the system is under heavy load
(however, there is ~300Mb of free memory and free ~50% cpu) master process
is not forking new processes or doing it in a very strange way. If i telnet
to port 143 it just opens the connection but no cyrus' prompt... it might
delay for 40-50 seconds. Meanwhile sendmail tries to deliver local mail and
opens many connections to localhost that eat memory, cpu, swap and then my
box dies. If I kill sendmail when there are 900 of them and then start it
again after 5-10 minutes it's ok... So i suppose there are very many
simultanous requests to master which it can't handle.
Has anyone experienced something similar? Maybe it's a Linux problem, but I
have no clue what to do.
