I would recommend to upgrade the FLARE to 02.23.050.5.711 and see if you are receiving the same alert.
I have this alert on my AX4-5F8.  I can't seem to get rid of it, and it makes the "Attention Required" constantly appear on the system.  However, there is not any "problem".  I have my SAN setup in full mesh, so for example a server has two dual-port HBA's.  One port of HBA1 goes to Brocade1, the other port goes to Brocade2.  And the same for the other dual-port HBA - one port of HBA2 goes to Brocade1, the other goes to Brocade2.  And I have to multiple SP ports going to each switch.  So obviously not every HBA port is going to be connected to every SP port.  But every server has multiple paths to the storage array so an HBA can fail, a Brocade can fail, an SP can fail....and it all remains up.  Anyway, I need to get rid of (or somehow "accept") this alert so that the storage doesn't constantly reflect a state of warning.  In the connection info, it displays the server, the HBA port with WWN, and then the list of SP/Port Status has some Active and some Inactive.
AX4: (0x720e) "Some server connections that are registered with the storage 
system are now inactive"
