We have several servers configured likewise, and haven't seen this 
problem on any of them.  The versions are slightly different:

Component Revisions


                CLI: 2.7-1 (Build #4944)

                API: 2.7-1 (Build #4944)

    Miniport Driver: 1.1-0 Beta (Build #9999)

Controller Software: 2.7-1 (Build #3170)

    Controller BIOS: 2.7-1 (Build #3170)

Controller Firmware: (Build #3170)

We have 2 other servers that are RAID-1 only, and they have both 
displayed this behavior about once every-other month between them.  The 
RAID-1 servers don't do much CPU processing, but shovel tons of packets 
between interfaces (including ipsec).  This is all anecdotal, of course; 
but the machines are all exactly the same age -- the only difference is 
the RAID configurations on them and the jobs they do.
