Connection is not torn down.


Potential resource exhaustion.


HTTPS server disconnects connection when in handshake.


You can mitigate this condition in either of the following ways: -- Wait for system to clean up lingering connections. -- Use tmsh to clean up connections. (Note: Sometimes this might not work as expected depending on conditions.) -- If this happens on the config-sync channel, use a different self-ip for config-sync on the affected device.

Fix Information

SSL server side handles this error situation by sending out all remaining egress data and sending a shutdown signal to lower filters.
