Injection can not work continually

[Boeing738ng]

If the transmitter send injection packages continually in a rate of 100 packets per second, log_to_file on the receive can only run normally for several minutes, then it would not have any output at all.

I checked usage of the memory, and I found that almost all space of the memory had been buffered.

I want to get CSI informations for several hours.
How to fix it? Is there some parameters I can set to empty buffers automatically?

This likely means that you're injecting data at too high a rate – faster than the NIC is sending the packets. Can you try using the delay parameter – e.g., send only a single packet per second – and see how long the connection lasts?

Thanks, I have solved the problem.

[dhalperi]

Thanks! – can you please say more about what the problem ultimately was and how you solved it?

@dhalperi
I just increased the scheduling priority of the process log_to_file, and now it can run continually without interruption.

@Boeing738ng Could you please explain how did you add the scheduling priority to log_to_file. Even I have the same issue on the buffer space availability. Thanks.
