RCA doesn't work with timeout

Hello experts,

I have finished updating our SolMan 7.1 from sp08 to sp11.

When I checked whether all features are working,

I found that Root Cause Analysis(RCA) is not working.

Please see the following images.

When it was the SolMan 7.1 sp08, RCA was working correctly.

Could anyone tell me how to resolve this?

Best regards,

Takashi Nasu
