[Dovecot] dovecot died

[tblader]

you may want to try increasing the number of files available for the system.
(Assuming your on linux).  You'll have to google for the exact location but
they should be something like file-max or inode-max under /proc

On Suse...
# find /proc/sys | grep file
/proc/sys/fs/file-max
/proc/sys/fs/file-nr

# cat /proc/sys/fs/file-max
50716
