Any idea how I might verify what the problem is?  I&#39;m not seeing anything popping up in the error logs and I&#39;m not able to reproduce this myself, I&#39;m going off reports from customers<br><br><div class="gmail_quote">

</div>I don&#39;t think that is the actual issue if your cluster members have time in sync, since session functions use this SQLs (program/include/rcube_session.php):<br>
- db_destroy (kill session; logout etc): DELETE FROM %s WHERE sess_id = ?<br>
- db_gc (garbage collector): DELETE FROM %s WHERE changed &lt; %s<br>
<br>
Our problem is that cached information (cache_messages, etc) does not get purged automatically, but I don&#39;t know what is the deal about that.<br>
