[NETCONF-1175] TCP session is hanging when NETCONF session is dead

Duplicate — Wed, 1 Nov 2023 18:40:43 +0000

TCP session is hanging even when NETCONF keeplive did not get reply.

Steps to reproduce:

start ODL + start testtool
mount testtool to ODL (keepalive-delay=5s, default-request-timeout-millis=3000)
wait until connection-status is connected
block packets on testtool going from ODL to testtool `iptables -I INPUT -p tcp --dport 17830 -j DROP`
in worst case connection should be closed after 8s (5s + 3000ms) because keepalive does not get reply. However, keepalive is sent, nothing happens and connection-status is still "connected"
