"ndisc_cache: neighbor table overflow!" #512

Closed FFHener closed 5 months ago

FFHener commented 12 months ago

After flashing a new router for #511 this warn-message randomly appeared and dissapered again 2 times. I'm unshure where the root of this Error is so here are a bunch of Infos hopefully being helpful. The timeline was: I installed the router in the afternoon, it suddenly stopped working during evening, but was still reachable via IPv6-link local. During the night it suddenly worked again (according to monitoring), but I found similar error-message during a timespan of 10 min in the morning.

Initial logread and routes during the evening:

~# logread

As the problem accured again the other side magda reported the following in dmesg:

A symptom we saw together with ndisc_cache: neighbor table overflow is OLSR link quality oscillating between crap and good repeatedly within a minute. Which is weird because NDISC is supposed to be about IPv6.

FFHener commented 5 months ago

In the end the corerouter didnt received enough energy which caused a lot of weird behaviours. As this is solved im closing this issue for now
