[Dovecot] "service_count = 0" for "service dict" (High-performance mode)

Hi,

I'm running dovecot 2.1.17 with "Login processes" in "High-performance mode" as explained here:

service imap-login { service_count = 1

http://wiki2.dovecot.org/LoginProcess

but i thinks I should also set "service dict" in high-performance mode since sometimes the number of dict processes reach the limit of 100 (from default_process_limit=100) and I find these errors in the logs:

Sep 25 15:32:24 imap(info@xxxx), session=<z9N2SDXnIQCy71XC>: Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Connection reset by peer Sep 25 15:32:24 imap(service@xxxx), session=: Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Connection reset by peer

or

Sep 25 15:33:48 imap(info@xxxx), session=: Warning: read(/usr/local/dovecot-2.1/var/run/dovecot/dict): dict lookup took 5 seconds Sep 25 15:33:48 imap(editoria@xxxx), session=<3LpHZTTnDgBdJwmm>: Warning: read(/usr/local/dovecot-2.1/var/run/dovecot/dict): dict lookup took 5 seconds

Do you think will be better set:

service dict { service_count = 0

or default_process_limit=200 (instead of 100)

Thanks
