'tmsh show sys conn all-properties' shows connections whose idle time exceeds the timeout.
Connection does not tear itself down.
There is no pool member, and a TCP::close iRule activates (typically after a TCP::respond).
Make TCP::close conditional on pool failure, and rely on the pool failure to RST the connection rather than perform a clean TCP close.
The system now properly handles TCP teardown when TCP::close has already torn down the rest of the stack.
