When the /sys db tm.simultaneousopen variable is set to 'reset' or 'drop_connection', TMM may crash during a TCP simultaneous 4 way handshake.
Traffic disrupted while tmm restarts.
1. The /sys db tm.simultaneousopen variable is set to 'reset' or 'drop_connection'. 2. A TCP 4 way handshake (simultaneous open) occurs as described in RFC 793.
The crash can be avoided, while still mitigating TCP 4 way handshakes, by setting the /sys db tm.simultaneousopen variable to 'drop_pkt'.
