PI4 with packet injection: wlc->osh->pktalloced constantly increasing - is it an issue?

[tomer-avrahami]

Hi,

I am using a setup of two RPi4, one used as packet injector and the other as CSI monitor. I see that after ~420 packets, I can't inject any more packets - till reboot. It seems that I have some memory allocation issue, but I can't find it. I noticed that wlc->osh->pktalloced is increased with every packet (never decrease), could it be the issue? What should decrease this variable and free the memory?

Can you please guide me on which variables to look which might cause this scenario?

Thanks, Tomer
