Hi Paul,
Cheers for the advice, i've lowered it from around 10000 to
100 for the time
being. Restarting dbmail-lmtpd (40 processes) just free'd
me up 1.5gig
Kind Regards
James Greig

James, not normal at all. Someone else reported possible
leakage in the
lmtp daemon as well, so it's a definite suspect.
Until someone tracks this down consider lowering the
maxconnects setting
in dbmail.conf for lmtp. If necessary lower it to 1.
