Andrey/Kubilay, Thanks for the responses. I was actually able to grab 2 patches from markj that we are currently testing. The first is actually in Phab, maybe we can bribe markj to pick it back up :) https://reviews.freebsd.org/D2254 The second one actually gets into the NDP code and is similar to the one posted on the mailing list that you linked. It's a few months newer from May of 2013: https://people.freebsd.org/~markj/patches/ndp-locking.diff Initial testing is going well, I'll report back once we have more conclusive results. It appears based various threads and reviews that the issues are a bit nebulous as there are many locking issues in this code. Thank you to markj and others for going after the hot spots, and I've created a bug report to track the overall progress of this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205165 Also, I don't believe these issues have been present for too long. I see the entry deletion bug reported on 4.X/5.X, and that seems to be more related to the ndp binary itself. Our 8.3-RELEASE installs did not exhibit the race conditions in the kernel code. Thanks again!
