Hi,

 I am trying to setup a cyrus on CentOS 7 systems with a
 cyrus murder backend. Unfortunately I fail quite early while setting
 up the cyrus. 

 The Problem ist that a cyrus murder setup with an cyrus-imapd newer
 than 2.4.17 seems to have either problems with the imap proxy, or I am
 simply doing it completely wrong.  The Version 2.4.17 works with the
 config, version 2.5.8 or 3.0beta does not work.

 To track down the error, I have the cyrus running with a very
 minimalistic configuration. Even this configuration shows the same
 error. After creating a mailbox on the backend, all information is
 propagated to the frontend and the mupdate server. But the information
 in the frontend is garbled and the the proxyd process even crashes
 while accessing the mailbox.

 So new server, one mailbox on one fronted. Ctl_mboxlist shows the
 following:

 at backend:
/usr/lib/cyrus-imapd/ctl_mboxlist -d
user.wolf	0 default wolf	lrswipkxtecdan

 at the mupdate server:
/usr/lib/cyrus-imapd/ctl_mboxlist -d
user.wolf	1 imailbackend00!default wolf	lrswipkxtecdan

 at the frontend:
/usr/lib/cyrus-imapd/ctl_mboxlist -d
user.wolf	1 imailbackend00!defaultH�H��f� wolf lrswipkxtecdan

 The proxyd process at the fronted crashes while executing the info
 user.wolf command via cyradmin as cyrus-admin:

Jun 20 12:04:31 ilserv15 imap[73259]: Fatal error: Internal error:  assertion failed: imap/annotate.c: 1615: state->mailbox
Jun 20 12:04:31 ilserv15 master[73250]: process type:SERVICE name:imap path:/usr/lib/cyrus-imapd/proxyd age:1239.927s pid:73259 exited, status 75

 The wanted setup is one frontend server, one mupdate server and two
 backend servers with the following configs:

 Any hints why this is not working as expected ?

 Thank you in advance for any help.

Kind Regards,
