Can you see other strange symptoms on that machine?
For example very high system load but not high I/O?

We had similar issues with imap processes that are hanging in "D" state some 
months ago.
The problem was, or is a bug in the inotify mechanism in the linux kernel. Not 
shure if the bug has just been
fixed.

For details see here:

Thanks Steffen Kaiser ! I think not. The server is currently always 60% of imap processes 
in state "idling".

IDLE processes are like this:
root@server:/root# ps aux |grep imap
dovemail    617  0.0  0.0  23136  2260 ?        S    Dec15   0:01 dovecot/imap 
[Username1 IP1  IDLE]
dovemail    677  0.0  0.0  23104  2172 ?        S    Dec15   0:01 dovecot/imap 
[Username2 IP2 IDLE]
...

My "idling" processes are seen as follows:
root@server:~#  ps aux |grep imap |grep idling
dovemail   1141  0.0  0.0  16836  2148 ?        D    Dec15   0:01 dovecot/imap 
[idling]
dovemail   3375  0.0  0.0  16828  2120 ?        D    15:48   0:00 dovecot/imap 
[idling]
dovemail   4833  0.0  0.0  16828  2212 ?        D    15:49   0:00 dovecot/imap 
[idling]
...

Thanks!

Is it normal this large amount of connections in state 'idling' ?

If they actually using the "IDLE" command to wait for PUSH mails on much more 
folders than on the other server?
