Pretty sure merge mining HUC with p2pool no longer works - I've not found any blocks for a couple of months now with over 10Th, so have removed HUC from my nodes. Same thing with NMC actually - I'm wondering if it's the same problem, especially now that CRW merge mining isn't working either, as I know they were all coded by domob.
@ domob: Any chance you could have a look?
Thanks

not sure but hopefully domob can have a look.
As you seem pretty experienced i guess you understand that when merge mining, the merged mine coin is not sharing hash with p2pool miners, only sharing (like a pool) with the primary coin (bitcoin). So you are going up against DiscusFish (f2pool) basically solo mining. (afaik)
Hi snailbrain,
Yeah, I realize that I'm basically solo mining when merge mining. However, I've been getting errors on p2pool startup with HUC & NMC for some time now, but never took much notice until recently when I realized I'd not found any HUC or NMC blocks for months, & now CRW is giving me a similar error on startup I think I might have found a common problem between them all, especially as all three were coded by domob.
I've just finished doing some startup tests on my node & have collected the error logs of all three coins for domob to have a look at - it does seem to be a similar error with all three - so I'll PM him my results now.
Cheers

Following up on this, it turns out I was right about merge mining this & other coins not working with p2pool. Domob kindly contacted me with an explanation & a suggested resolution to pass on to the p2pool dev for implementation - which he has now done & I am testing now.
