Hi !<br>
<br>
I'm trying to fix an environment which has been growing without proper<br>
attention.<br>
<br>
There are about 7000 inboxes but only 5000 are active and the maxchilds<br>
parameter is set as "2000" causing a lot of timeouts when the clients try<br>
to connect. I thought as a first approach trying to increase this parameter.<br>
<br>
I have noticed that even with the "maxchilds" parameter set as "2000" there<br>
are about 2020 processes open, is this behaviour normal? The version in<br>
use is 2.4.12.<br>

Are there really 2000+ IMAP clients trying to connect? Try "ps -ef | grep imapd | wc -l".<br>
<br>
It's also possible that there is an IMAP client running wild, making hundreds of connections. The output of "netstat -nt" might show you if there are a lot of connections from a single IP address.<br>
<br>
If you really need to allow more connections, increase the maxchilds parameter. Beware that you don't overload the server, either with too much I/O or not enough RAM available! :)<br>
