Zitat von Marcus Schopen <lists@xxxxxxxxxxxx>:
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?
Ciao
Marcus
With maxchild=100 you can have at max 100 concurrent IMAP connections. If you need more you should raise this value. If your machine is able to handle this depends on what is actually done with this open connections and what other services compete for machine resources.
