[CentOS] memory leak in Centos 4.1 and 4.0

Centos 4.0 and 4.1 seem to have a memory leak somewhere and I can't find 
out what is doing it.  I think it may be dovecot.

I have installed hundreds of Linux machines, centos/redhat/suse in the 
past as firewalls and mail relays and use the same/similar  methodolgy 
and config for each.

I have found that since Centos 4.0 and 4.1 came along machines that have 
run well for years and months, suddenly and systematically start running 
out of memory after a few weeks/months of uptime.

The symtpom is the load average goes up and up as the machine creeps 
into swap usage and eventually the machine has to be rebooted....

this only happened with the introduction of Centos 4 and of course that 
means Dovecot for the IMAP server....


Anyone else seen this,
