Wow, 10 children - I hope you have at least 2 REAL CPU's/cores (not some wanky
Intel "Hyperthread" thing that just /says/ it's got 2 CPU's/cores...but it's
not really) and a *LOT* of RAM (2GB territory on a dedicated server, double
that if this box is sharing with other things). Are you sure you're not
hitting some resource limit?
On my systems I have a restrictive default config for all accounts that don't
have a login (eg, postfix, bind, etc) which bit me on the butt when
MailScanner needed more file handles than I was allowing it and resulted in
the sort of "hang" you describe above when the mail queues got big. Once I
upped the file handles limit everything was peachy again. There were plenty
of messages in the logs (/var/log/messages and /var/log/kernel.log on Linux)
which gave me the necessary clue.
Success is getting what you want; happiness is wanting what you get.
