I'm just guessing - but reading that warning it appears to me that 
Dovecot is saying that as it is configured, it can consume more O/S 
resources (I assume fd is "file descriptors") than the O/S is currently 
configured for.  So you need to DECREASE your dovecot max processes to 
decrease the (potential) system demands - or increase your O/S settings.
