[imp] IMP Problems after Server reinstallation

Good afternoon list users,
I am new on this list and having a weird problem with IMP ever since we
had to reinstall one of our servers with the latest CentOS 4.7
distribution. Everything else Horde related works normally (Calendar,
Addressbook).
After installing the CentOS 4.7 server with packages from centosplus
(mainly PHP and Apache) IMP suddenly showed some weird behaviour when
dealing with IMAP connections. As soon as a user tries to log in the
server receives a GET request (shown in the access_log) and the client
jumps to "Waiting for <server> ...". This is the last thing that will
happen - no entries in any logs (access_log, error_log, horde.log,
system logs - all settings to debug) about what is delaying the
connection. Sometimes just clicking on a link or logging in again fixes
that for a couple of page loads but then goes back to the delays.
Also, as soon as I restart the apache server, the connections work
normally for a couple of seconds before everything slows down again. I
noticed that, when the connection is currently in the "Waiting" state
for the client, closing down apache would cause some PHP files to be
downloaded (sidebar.php for example). I assume that is normal when the
server shuts down but yet interesting since it appears to be the last
file being accessed before the wait occured.
Long story short: I think I got it down to a problem in the IMAP
requests. So I tried using an imapproxy to see if it is related to the
imap connections - no change - which isn't a surprise since the IMAP
server runs locally for authentication and mail access for the webmail
clients.
I tried with a different webmail client and everything worked fine.
All this is happening on server 1. The second server, which is still
running the older version of CentOS, doesn't have any problems as
described. Both servers share the same configuration base for the
webserver and other PHP related things (Zend, php.ini etc.). The only
difference are the installed program versions. Also the horde framework
and application configurations are the same on both servers.
I did some searching on the web but none of the solutions or ideas
really helped fixing this problem. I attached some information at the
end of this mail - if you need any other information please let me know
and I will send it in.
Thank you for your time, I just don't know where else to look for the
problem.
Cheers,
Sebastian
