idled isn't IMHO probably not the cause hereover: 
----  snip  ----
1001#po-a:grep idled /etc/cyrus.conf 
  # this is only necessary if using idled for IMAP IDLE
#  idled         cmd="idled"
1002#po-a:
----  snip  ----
And that wasn't changed in years.

I also don't believe in simple iSCSI bugs - it's IMHO old enough and too
much used for that.
