Same problem here, on different machines. But only with mdadm 2.6, with 
mdadm 2.5.5 no problems.

First machine sends direct after starting mdadm in monitor mode:
(kernel 2.6.20-rc3)
-----------------------------
event=DeviceDisappeared
mddev=/dev/md1
device=Wrong-Level

Personalities : [linear] [raid0] [raid1] [raid6] [raid5] [raid4] 
md1 : active raid0 sdb2[1] sda2[0]
      3904704 blocks 16k chunks
      
md2 : active raid0 sdb3[1] sda3[0]
      153930112 blocks 16k chunks
      
md3 : active raid5 sdf1[3] sde1[2] sdd1[1] sdc1[0]
      732587712 blocks level 5, 16k chunk, algorithm 2 [4/4] [UUUU]
      
md0 : active raid1 sdb1[1] sda1[0]
      192640 blocks [2/2] [UU]
      
unused devices: <none>
-----------------------
and a second time for md2.
Then every about 60 sec 4 times

event=SpareActive
mddev=/dev/md3

******************************

Second machine sends about every 60sec 8 messages with:
(kernel 2.6.19.2)
--------------------------
event=SpareActive
mddev=/dev/md0
device=

Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]

md2 : active raid5 sdh2[7] sdg2[6] sdf2[5] sde2[4] sdd2[3] sdc2[2] sdb2[1] 
sda2[0]
      6858880 blocks level 5, 4k chunk, algorithm 2 [8/8] [UUUUUUUU]

      235086656 blocks level 5, 16k chunk, algorithm 2 [8/8] [UUUUUUUU]
      
unused devices: <none>

--------------------------

Both machines had nerver seen any spare device, and there are no failing 
devices, everything works as expected.
