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=<xKxSSDXnwABb/1Ql>: 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=<M8FITTXnwABb/CM9>: 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
