Incomplete mdstat output

Since Nov 30 2007 this server has had raid green excluding two red events -
on on the 19th and then just a few minutes ago.

They read identical to normal with the exception of the very top.  Green:

*green md0 Status OK
green md2 Status OK
green md1 Status OK*

and the first red

*red md1 Status OK*

and the second red

*red md2 Status OK*

Now both the red and green show the informative part identically:

============================ /proc/mdstat ===========================

Personalities : [raid6] [raid5] [raid4] [raid1]
md0 : active raid1 sdb1[1] sda1[0]
      104320 blocks [2/2] [UU]

md2 : active raid5 sdc1[2] sdb2[1] sda2[0]
      4192768 blocks level 5, 256k chunk, algorithm 2 [3/3] [UUU]

md1 : active raid5 sdc2[2] sdb3[1] sda3[0]
      151894016 blocks level 5, 256k chunk, algorithm 2 [3/3] [UUU]

unused devices:

============================ End of file ============================

In the past I have found these as legit red/yellow causes:
Yellow...
   green md0 Status OK
   green md1 Status OK
   green md2 Status OK
   yellow md3 resync in progress

Red...
   green md0 Status OK
   green md1 Status OK
   green md2 Status OK
   red md3 Disk Failed

Any idea as to why mdstat doesn't say the top part isn't saying anything?
This may be more of a ##linux question but I was hoping someone had seen
this before.
