In rare BigIP configuration scenarios, TMM may crash during its startup process when the tunnel configurations are loaded.
TMM crash in rare race conditions.
During TMM startup, a tunnel is created, then immediately removed during the configuration load period, when TMM neighbor messages may be in flight via the tunnel. When the race condition fits, the neighbor message may land on an invalid tunnel.
TMM no longer crashes on neighbor messages during the initial tunnel config load process.
