Make sure you have sized the beancounters (resource limits) for your
applications and workload. With the default beancounter settings, a
default centos5 install of postfix (100 process max -- per service, ie
100 smtpd and 100 smtp) or dovecot (100 each for imap/pop3, etc.) you
will run into limits very quickly.
Using vzsplit helps a lot.
