This testcase triggers a bug in the BSSMAP reset logic that tricks
the MSC into a deadlock situation. The bug can only be triggered on
a freshly started MSC, otherwise the testcase will not have any
effect at all. That's why it its important that this is the first
testcase to be executed. If the IUT (MSC) is still affected by the
bug. It will enter the deadlog situation and all subsequent testcases
should fail until the IUT (MSC) is restarted. The matching real-life
scenario would be that the MSC restarts. The BSC is not informed by
the restart, so it continues to make connections (which fail) until
it notices that the MSC was down and the execution of a BSSMAP reset
procedure is required.
