I just managed to trigger it again so probably no :) This is on 5.10.0-13-amd64/5.10.106-1 with babeld 1.9.1 and bird version 2.0.9. While it's happening bird prints something like the following every once in a while: I/O loop cycle took 6793 ms for 6 events I get 500-2000ish events from `ip -6 monitor` over a 10sec interval as opposed to the 80-150k I usually see. > Hmm, I've definitely had issues with dnsmasq not handling lots of route > updates well.

On the other hand if I kill babeld the insertion speed seems to go back up again. So that would seem to suggest dnsmasq isn't the problem. Interestingly I can't seem to trigger it by just (non-gracefully) restarting bird so there must be a trigger other than just lots of route insertion activity going on. For completeness' sake: I added a babel protocol to my bird config before this triggered again but it's not involved in the main bgp routing table only a tiny isolated one nor is it handling any of the interfaces babled is on. For now I'm assuming this is not causing to the problem. --Daniel _______________________________________________ Babel-users mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
