Failed to initiate scan task for [some machine]. Scanning Failed

Failed to initiate scan task for [some machine]. Scanning Failed

Hi,
I have created support ticket  #5111680  yesterday, but nobody answered me yet

On some clients when I perform an asset scan I get an error Failed to initiate scan task for [some machine].  Scanning Failed .
On another machines everything is fine.

When I checked invsummarylog - I found this error Data storage error occured while populating asset data. Scanning failed

How to solve this problem? 
Thanks in advance
