Hi.

I have a database with a bucket of 816 large pairs but when i try to delete it boltbrowser shuts down with the resulting error:

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 commented 5 years ago

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

br0xen commented 5 years ago

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.

Okey :) I can file it on the boltdb-page instead. Thank you.
