Claim 14:
15. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
monitor a transmission control protocol (TCP) session with an other network device;
identify a TCP header, a socket of the TCP session, and one or more of a set of ingress packets or a set of egress packets;
inspect the TCP header, the socket, and the one or more of the set of ingress packets or the set of egress packets to identify session information,
wherein the session information includes negotiated TCP options associated with the TCP session and one or more of a finish packet or a reset packet;

detect a TCP session flap based on the session information including the one or more of the finish packet or the reset packet;
store, in a dead TCP session list, data identifying the session information based on the TCP session flap being detected; and
utilize, based on the TCP session flap being detected, the negotiated TCP options to identify an out-of-sync issue,
wherein the out-of-sync issue corresponds to the network device having selective acknowledgement enabled and the other network device not having selective acknowledgement enabled.
