VERSION: 6.4, 7.1, 8.0 
The customer is using MP configuration with network failover/failback.  After the primary network interface is brought
down,   they try to shutdown some of their application servers.  Since MIB request is not working,  they kill the
servers by "kill pid" (SIGTERM).   This leads to a BB dead lock situation,  with pages of the following
errors in ULOG:

        BRIDGE.9206: WARN: Could not lock USEM
        BRIDGE.9206: LIBTUX_CAT:746: ERROR: Cannot lock Bulletin Board
This problem seems to related to secondary event brokers running in the slave node,  it does not happen using simple
testcase without TMUSREVT/TMSYSEVT.
