I have upgraded an RB750 to 6.31. Since the upgrade, one of the ethernet ports is flapping "no link"/"link ok" every 10 seconds and is obviously showing very poor performance. The log also registers link down, link up events. The LED stays lit. The ethernet in question is connect...

So, using NTP on CCR is sure to be the largest contributing factor, but it's not 100% limited to that scope. While unrelated bugs can't be ruled out, this specific issue is tied to the processing of a leap second event from the NTP subsystem to the linux kernel. So it can not happen if you are not ...

Given what happened. I would try and simulate the addition of a leap second on the CCRs well before june 30.

Now, tell me I did not warn you.

There is at least a report of spurious leap seconds observed in Italy on march 31, 23.59.60, with a possible explaination: http://lists.ntp.org/pipermail/pool/2015-April/007338.html Given what happened. I would try and simulate the addition of a leap second on the CCRs well before june 30. cheers, L.

Since it has been mentioned, there *is* something weird concerning leap seconds that *could* be related. We had a number of Linux hosts incorrectly adding a leap second last night: 2015-04-01T01:59:59.003687+02:00 fe-a-01 kernel: [9475817.256006] Clock: inserting leap second 23:59:60 UTC we are stil...
