fsck - reference errors??

[GreenMatter]

I've got some index error in Sensei DB. That made me to run fsck and results are:

How can I get them repaired?

Ok, I've run fsck in single user mode and all is fine.

It seems that fsck reference errors are "normal" when scan is performed on running system...
