I've pulled everything fresh from trunk in my quest to get multiple BTS's working on one E1 card.  :)  However, I'm seeing a core dump when I start osmo-nitb in the box now.

A BT is available here:

This is in a configuration where I only have one BTS configured.  Though I get the same issue if I have more than one configured too.

Thanks,
Gus
