SCOM alert for SourceOne: Too many flagged index sets

Hi,

SCOM just displays an erros for both my APP servers: Too many flagged index sets.

Alert descciption: There are too many flagged index sets found in native archive "Company-Native-Archive (15 Flagged)".

I checked my Indexes and Volumes and I cannot see anything wrong.

What should I do to make these erros  dissapear? Where can I find these erros on ma APP servers?

We have a version 7.2.2.2028.

Thnx in advance,

Toza
