timeouts when connecting to imap server

[Timo Veith]

Hi! 

I am still having the problem, isn't there anyone who has a hint for me? I 
changed the io scheduler from cfq to deadline, raised file descriptor 
limit to 300000 and still have no betterment. :(

I installed the nagios check on the mail server itself to exclude network 
problems and checked the imap service on both interfaces (localhost and 
on the external ip). I also did this in parallel and noticed that when a 
timeout happens on one interface it is not constraining a timeout on the 
other interface, too.

How can I tell why it sometimes takes so long until a imap process 
responds?


Regards,
Timo
