Frontend becomes unusable when one backend dies

[Frank Richter]

Hello,
I'm running a simple standard murder environment (v2.3.8 on Linux x86_64) 
- one frontend, two backends. If one of the two backends is down, 
then the frontend (and the whole system) becomes unavailable after some 
minutes:

On the frontend imapd's and pop3d's are started till the maximum
count (maxchild in cyrus.conf) is reached. It seems that they're still 
trying to reach the "dead" backend server.

Maybe it is a timeout issue - I let the default client_timeout 
(10 seconds) in imapd.conf. Is this value relevant for this behavior?

Thanks,
Frank
