This is using layer2 ethernet, and the peer delay mechanism. The following output With a large chunk of similar output snipped out of the middle. ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -0 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -2 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -2 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 1 s2 adj -0 path delay 2246 ptp4l[9130]: master offset 1 s2 adj +0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 1 s2 adj +0 path delay 2246 ptp4l[9130]: master offset 1 s2 adj +1 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 1 s2 adj +1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj +0 path delay 2246 ptp4l[9130]: master offset 0 s2 adj +0 path delay 2246 ptp4l[9130]: master offset 1 s2 adj +1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj +0 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -1 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -1 path delay 2246 ptp4l[9130]: master offset -1 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: master offset 0 s2 adj -1 path delay 2246 ptp4l[9130]: recvmsg tx timestamp failed: Resource temporarily unavailable --- Here, recvmsg doesn't throw a fault?

later on a different error throws a fault and suddenly everything is better. Is that behavior in the Middle possibly caused by some faulty state that wasn't cleared? I am not sure, but those path delays And values seem incredibly wrong. I think it's because somehow one of the sequence numbers got Out of order and messed up. I am going to try and take a look at that code and see if I can find the issue, But I am wondering if you've seen behavior like this. - Jake |
