Hi,

Hi,

In 1.10.2-16.el7_5, that code looks pretty similar. NetworkManager
should either log

    "router solicitation sent"

or

    "failure sending router solicitation: ...

for every RS that gets send.


Possibly the logging message was suppressed by journald's
ratelimiting

Most likely.

(as the journal would tell you, if that's the case). Make sure to
disable rate-limiting, see [1].

Is it really necessary to actually see the messages in the journal at
this point?  Doesn't the packet trace and CPU load of NM from my
previous message sufficiently prove that NM is storming RSes?

Cheers,
