&lt;p&gt;This can result in a disconnection if two peers drift away such that they use different channels. It may also lead to a disconnection if the connection event counters become different, and a control procedure involving an instant is executed.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
