Yup I have now: # # Default number of child processes to start. # NCHILDREN = 10
# # Maximum number of child processes allowed. # MAXCHILDREN = 50 # # Unused children to always have availale. # MINSPARECHILDREN = 5 # # Maximum unused children allowed to be active. # MAXSPARECHILDREN = 10 # # Child process is restarted after handling this many connections. # MAXCONNECTS = 10000 # # Child process will restart after this many connection errors. # MAX_ERRORS = 500 # # Idle time allowed before a connection is shut off. # TIMEOUT = 60 I think thats much better now.But still it makes me wonder why does it just hang and never recover. But maybe I don't see anymore hangs.

Jani, A max of 10 children is very, very low. Set it to 100 or 200 or even higher if your sql server can handle it. I'm not sure why it doesn't recover. Jani Partanen wrote:Okey, I have logs now from last hang. It looks like server was running out of childrens, am I right? So I have play around with configs now and bumbed up thouse settings, also I did change imapd timeout to 4000 what was 300, it did already helped much and imapd didn't hang anymore every day. But why does it hang and never recover from this? Also restarting it requires 2 tries.
