imapd process hanging

We recently started running Cyrus for our mail system.  We have started
to encounter some issues where an imapd process will hang, and start
consuming CPU.  When I kill the imapd process (using "kill -HUP <pid>"
or "kill <pid>"), the master process dies, and restarts.

I would like to avoid taking down the entire Cyrus service (it only
takes about 15 seconds to restart, but that is still downtime) when we
have a hung process.  Does anyone know of a way to terminate a
stray/hung imapd process without taking down the master process?
