Yup, could be the same problem. Look for lines like these in your mail 
log:

Mar 21 04:01:14 bx dovecot: pop3-login: Error: socket(anvil) failed: Too 
many open files
Mar 21 04:01:14 bx dovecot: pop3-login: Error: net_connect_unix(anvil) 
failed: Too many open files
Mar 21 04:01:14 bx dovecot: pop3-login: Fatal: Couldn't connect to anvil
Mar 21 04:01:14 bx dovecot: master: Error: service(pop3-login): command 
startup failed, throttling
Mar 21 04:01:15 bx dovecot: imap-login: Error: socket(anvil) failed: Too 
many open files
Mar 21 04:01:15 bx dovecot: imap-login: Error: net_connect_unix(anvil) 
failed: Too many open files

I either ssh in and do "service dovecot restart" or I toggle the POPS 
server off and then back on in the admin GUI to get it going again.

I'm puzzled why the Active Monitor script can't seem to restart Dovecot, 
when I can restart it manually.
