Current state: problem (non-blocking)

Hi List,
I have installed two modules of firewall NGX (R60) HFA_03
and my SmartCenter
is running over SecurePlatform
My cluster-XL is set in High Availability.
 When I check the integrity of the cluster get (below) the
return of one of
its members with problem.
In another member of the cluster that's OK with the same
command.
What does this mean? How can I fix this?
Thank you for any help.
