Interrupted system call

[TomerElya]

I'm sending udp packets at an extremely fast pace. On the other end I'm listening using zsocket like so:

err = zs.Listen(func(frame *nettypes.Frame, frameLen uint16, capturedLen uint16) {
ln:= frameLen
mPay, mOff := frame.MACPayload(0)
ln -= mOff
udp := nettypes.UDPPacket(mPay)
udp.Bytes()
atomic.AddUint64(&packetCount, 1)
})
if err != nil {
    fmt.Printf("error:%v\n", err)
}

And after a couple seconds it crashes with "interrupted system call"

I'd love some guidance, if you may, on how to use it properly or clarification on what I'm doing wrong?

Thanks!
