Description (partial)

ASA running Site to Site VPN tunnel, when tunnel gets terminated the connection associated with this tunnel stays in the conn table instead of immediately getting torn down.
After testing normal conditions the ASA should directly tear down the connection after the tunnel is down and it yields the same syslog message .

After testing in the lab the issue was reproducible in both 9.8(4) and 9.6(4) interim " recommended versions" 
issue was not seen in 9.12 interim.
