( https://gerrit.osmocom.org/c/osmo-msc/+/38513?usp=email ) Change subject: Release BSS connection when CC transaction fails ...................................................................... Release BSS connection when CC transaction fails When the creation of the transaction structure fails, the MSC will send a RELEASE COMPLETE message. This patch ensures that the MSC_A use counter is decremented, so that the BSS connection is released, if it is not used by any other transaction. Without this patch, the msc_a_fsm would wait 5 seconds for an initial transaction before releasing the BSS connection.
