RIPE Atlas

Hello,

the logs for my probe (version 1) show that is has been disconnecting
very regularly every 2 hours. The uptimes are always +/- 1 hour 50
minutes, followed by a disconnect period of 5, 8, or 11 minutes.

Out of my last 25 connects, 20 are like that. 3 have double the uptime
(about 3 hours and 50 minutes), only one has almost 24 hours, and the
current one is 6 hours and counting. The disconnects there were, again,
5, 8, or 11 minutes.

However, I to not notice similar disconnects as a user of the same
network. I sometimes listen to online streams for more then 2 hours
without interruption. I work on my computer for more than 2 hours and
don't notice these interruptions of my internet access.

It's all IPv4; no IPv6 here. The controller is ctr-fnc01.

What could be the cause of these log entries?

Hi,

Maybe you can mention your probe ID. That makes it easier to figure out
what is going on.

Your probe seems to reboot every two hours. V1 probes suffer from memory
fragmentation, so when the ssh connection breaks, they often reboot.
However I cannot find anything related to that in the logs.

A reboot can be caused by a power failure. Do you have anything that
might be causing that?

Alternatively, there may be a software bug that triggers the reboot.

Other V1 probes that connect to the same controller seem fine. So either
you probe gets a specific measurement that triggers a bug, or there is a
power issue.

How is the probe powered?
