Description
If sending a CM SERV REQ that's invalid, I get
<000a> a_iface_bssap.c:699 Rx BSC DT: 00 15 57 05 01 03 17 0f 05 24 01 01 50 09 21 26 24 10 32 54 76 98 0f <000a> a_iface_bssap.c:629 Rx MSC DT1 BSSMAP COMPLETE LAYER 3 <000a> a_iface_bssap.c:291 BSC has completed layer 3 connection (conn_id=1) <000a> a_iface_bssap.c:311 Unable to parse element CELL IDENTIFIER (wrong field length) -- discarding message!
but the MSC doesn't close the SCCP connection. It also doesn't send AUTH REQ or any other L3 message, basically keeping the radio channel open for no reason at all.

It is likely that this got fixed by http://git.osmocom.org/osmo-msc/commit?id=e3d3dc6ea218a07161eeb80ae864a96bef2d8e61 but worth testing before closing this.
