Hello B Buhlig, Your mail wasn't delivered to me, but I've just found it in the archive on SourceForge. I don't know why it was not delivered but I remember such accident has ever happened several times.

If so, I don't have such expensive system and cannot reproduce nor test. Actually this message is a kind of hook to debug, and I don't expect that users will see the message. Anyway it must be a problem of aufs'. Currently I don't have a good solution to address it except one. I'd suggest you to try disable CONFIG_AUFS_DEBUG. It will set ->migragepage() pointer to NULL, so the message won't appear. But I have to tell you one thing. I don't have tested aufs with such configuration and NUMA systems, so I am unsure disabling CONFIG_AUFS_DEBUG will solve your problem. It is just a hope/guess/suggestion (sorry I don't know correct English word). I'd ask you to test with disabling CONFIG_AUFS_DEBUG if you can. J. R.
