Hi All,
We are running QNX on a ISA CPU card embedded in a monitoring device.
We are finding the the network card stops transmitting entirely at variable
points in time. The nicinfo command show that the nic is still recieving
packets, however it does not transmit again until the system is rebooted.
The nicinfo only shows one bad txd packet (Shown below). If anyone has any
reccomendation or suggestions as to what could be stopping the nic from
transmitting, could you please let me know. Also if you’ve encountered a
problem similar to this could you let me know.
