Oh my, ok. Well, I guess I've never worked with a DB that was large enough to run into something like that. I'll try to find time to look into it, but it honestly looks like it's an issue with boltdb, since that's where the error is thrown...

[tomaswallentinus]

Okey :) I see the error is already reported to the boltdb-page. So you can ignore it :)

[br0xen]

Oh well, I'm not sure if it's actually a boltdb issue or a boltbrowser issue... They may just send you back to me. :) Sorry I've been extra busy with work lately so just haven't had a chance to dig into it.
