Updated to 23.11...now log (general) is full of Limiting ICMPv6 neighbor discovery redirect output notices

hey all,
just updated (a few hours ago) to 23.11...
Update went thru smootly, all packages kept working...
BUT:
I am wondering about entries in System logs (general). Here I find a whole bunch of
Limiting ICMPv6 neighbor discovery redirect output Messages (limiting iE from 254 to 94 packets/s).
What does that mean? Why didn't 23.03 show any of that? Is there anything I can do to stop this (either change some settings or -if nothing serious is happening- stop those messages...thy spam my logs)?
Thanx in advance! :)

Going to 24.03 ?!!
No, wait ....
Your pfSense itself should ask for an even better solution :
-
I assume you mean 24.11 and 24.03?
Seems like you have something sending way too many discovery packets. Or maybe a loop. I would grab a pcap and see what's actually being sent there.

@stephenw10
yes, I meant 24.11 of course....
I'll have a look...
Thanks -
hey all,
I could narrow it down...
found my zyxel switch was causing the problem...it is (I guess) another bad IPv6 implementation. So I offed my v6 Interface on my xs1930. Still reachable with v4 and no more spamming my logs.
Thank you for your hint @stephenw10 :)
