&gt; I think it would be useful to get a full pcap from the time yoy start OpenBSC<br />&gt; so we can do a more detailed protocol analysis of what fails..<br />&gt; <br />&gt; Attached is a pcap file captured with bsc_hack -p.  I let it run until there was no more &#39;action.<br /><br />Capture it with tcpdump please.<br /><br />There isn&#39;t much info in what you sent.<br /><br /><br />     Sylvain
