[imp] Imp and simultaneous usage

[Kevin Konowalec]

We have a group of users that are having multiple users accessing the  
same Cyrus IMAP account through horde/imp (latest stable releases of  
both) simultaneously.  They're basically doing the same job and  
dealing with incoming requests from the same pool of emails and are  
wanting to use the same account to keep things organized.  They have  
been complaining that there are times when Imp will just sit there  
and spin its wheels for no apparent reason.  Would this be a result  
of more than one person trying to access the same account at the same  
time?  Is this kind of usage not advisable?  If so, why?  If this  
SHOULD be doable then can anyone suggest what might be hanging things  
up?

On an slight tangent... there are a number of things that could be at  
fault when a user experiences a problem.  There could be an issue  
with the mail server, the IMAP proxy, the memcached servers, or the  
horde servers themselves.  For large clustered installations it gets  
tough to be able to diagnose where the problem actually is.  Has  
anyone come up with a good way to monitor the health of the entire  
system to be able to better keep your finger on the pulse?

Thanks
