I have around 1800 imapd processes...
I think that's what happening, the processes are doing something. But, if I 
want to stop, whatever someone is doing, how do I do ?
I thought cyrmaster would have killed all theses processes.

My cluster script can not wait one minute or two before to switch on th over 
server !

Did you also try a restart ?
I think, it's the same, all process remains up, with the old config, until 
they end, either because the client has deconnected or a timeout happened.

Anyway, here, I don't know why lmtpd does not accept connections anymore.

Perhaps should I not use prefork (2 or 5) processes in my /etc/cyrus.conf for 
all theses processes.
