[Dovecot] 1.0alpha1: too many open files

Help...

Dovecot 1.0alpha1 hung up today with nothing working and the following spewing to my syslog:

pipe() failed: Too many open files

My setup: Solaris 9, just using imap, mbox format. The various "max" settings in dovecot.conf use the defaults. Suggestions on what to change in fovecot.conf to keep this from happening?
