netmap crash with tcpreplay #168

Closed morphyno closed 9 years ago

morphyno commented 9 years ago

Not sure if this is a netmap or tcreplay issue. I came across this while running tcreplay 4.0.5.

Had to reboot the machine to recover.

From the call stack, it appears to be coming from an interrupt, and not touching any tcpreplay code. I suggest posting the trace on the netmap support site.
