Hi Daniel,
Thanks a lot for your answer!
I'll create a script to check this every minute, and restart those service
in case of death.
What can be the root cause of this? Can this happen because of the night
backup process, pushing the disks to have higher I/O? (higher is less than
30%, but is higher than the usual, that is almost 1%)
Thanks again, and best regards,
HeCSa.

Storage Server fails means that roundcubemail is not able to community<br>
or authenticate with the backend (aka imap server port 143).<br>
<br>
I would check the following points<br>
* is guam running (systemctl status guam). Guam is the imap proxy <br>
sitting<br>
in front of cyrus.<br>
* is cyrus-imapd server running (process table)<br>
* do you see any authentication related error messages from cyrus<br>
* is kolab-saslauthd and/or dirsrv running correctly?<br>
* is kolabd running?<br>
<br>
Another thing could be that guam/cyrus is running but the kolabd server<br>
has not created the mailbox yet. Restarting/Checking kolabd might help<br>
(as well checking the pykolab logfiles). Otherwise run "kolab sync" via<br>
cli to execute the mailbox sync/creating run manually.<br>
