There seems to be an issue with the Unobtanium daemon & p2pool merge mining. While using the daemon on Xubuntu 14.04 64bit I am not receiving any merge mine payments at all, but if I switch to using the QT wallet - payments resume as normal. I've tested this over a 4 day period, it is constant. I get no errors when compiling the daemon or QT wallet as well as no errors in my p2pool logs - everything appears to be working fine, but the payments are not appearing in my wallet when using the daemon. Both the QT wallet & daemon use the same startup command & wallet database. I've posted in the p2pool thread about the issue:

I'm not sure if the issue is the same on other OS's.
Thanks.
EDIT: Issue raised on github.
