After a specific sequence of packets resulting in sending a RST packet, TCP connection was kept alive and sent another RST when connection expired.
2 RST segments is sent to the client instead of 1. In addition, the TCP connection was kept alive until the sweeper cleaned it.
A specific sequence of packets (a second SYN segment within the TCP window) is received by a TCP connection.
There is no workaround at this time.
TCP sends a single RST for specific sequence of packets
