Hi, my cyrus/imap starts hanging (I get timeouts on port 143) whenever a user is connecting to 120 mailboxes from a single IP and holding these connections for some time. The machine (KVM, 4 GB RAM, 4x2,1 GHz CPU) doesn't have hight load or is swapping therefore I'm a little bit surprised about this behavior. SERVICES { ... imap cmd="imapd -U 30" listen="imap" prefork=4 maxchild=100 imaps cmd="imapd -s -U 30" listen="imaps" prefork=4 maxchild=100 ... } Would maxchild=150 solve it and would the work out with the given VM setup?
