HTTP or HTTP2 virtual server receives a request and tries to create a connection to the server. If this connection establishment fails, the connection to the client is torn down. This core occurs when trying to abort the clientside connection.


TMM cores, failover condition occurs, and traffic processing can be interrupted while tmm restarts.


-- A virtual server with HTTP profile is created. -- HTTP2 profile may or may not be present on the virtual server. -- An httprouter profile is present on the virtual server. -- Connection establishment with the server fails.



Fix Information

A TMM core no longer occurs under these conditions.
