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.

HTH,

James
