You are right, it looks as if some p2pool miners abandoned merged-mining, or they simply don't know anything about Namecoin Core. Is there a mailing list of p2pool miners or anything?


What's to know? Has the way NMC is merge mined with p2pool changed?

Those 2 blocks are a long, long time ago - namecoin-core has undergone many changes since then - I think it's too coincidental that none have been found for such a long period of time.

As far as a mailing list for p2pool - none that I'm aware of, only the p2pool thread or the merge mining thread:

https://bitcointalk.org/index.php?topic=18313.0
https://bitcointalk.org/index.php?topic=1008100.0

Or the p2pool repo of course.

Edit: I just realized - that's 3 months! I know for a fact that many p2pool users are merge mining NMC, myself included.

Seems we have a small misunderstanding here. I was talking about two different things within one paragraph.
Let me clarify (already posted at bitcointalk):

2015-08-02 23:21 UTC, NMC block 242312, mined by ghash.io. This was the last time an old NMC client was able to successfully mine a non-orphaned block.
2015-10-13 21:17 UTC, NMC block 253122, mined by p2pool miner 1GqdAgC1zmzLFMg3XyYctSECWUjkbT7Nv9 using the new Namecoin Core client.
2015-10-19 05:10 UTC, NMC block 253874, mined by p2pool miner 14N4xNSDtNYatfCgHhyRaAhdZtaczUBnAa using the new Namecoin Core client.

I do not understand what the problem is. I see these error messages:

Possible fix at https://github.com/namecoin/namecoin-core/issues/50 (thanks to Daniel). Can you see if this fixes your issue?

Just in case someone comes across this thread and misses the BIP9 discussion. It has partially turned into a p2p sharechain and Merged-Mining-2 discussion as of this post: https://forum.namecoin.org/viewtopic.php?p=16153
