Description (partial)

FTD Lina traceback in datapath due to double free

Additionally, the system reports the Syslog ID 419002 on ASA

Double free can occur when individual NIC transmit buffer is overloaded.

In this case, a routing loop caused many instances of the syslog "%FTD-4-419002: Duplicate TCP SYN from outside"  to be sent to the syslog server, which resulted in the transmit buffer overload.
