SparesMissing event

Hi all,
I got this message from mdadm --monitor when I restarted one of
my servers this afternoon:
SparesMissing event on /dev/md/0:blah
[snip]
Personalities : [raid6] [raid5] [raid4]
md0 : active raid6 sdg[5] sdb[0] sdk[12](S) sdd[2] sdl[10] sdi[7] sdh[6]
sde[3] sdf[4] sdc[1] sdj[8]
15624900608 blocks super 1.2 level 6, 512k chunk, algorithm 2 [10/10] [UUUUUUUUUU]
bitmap: 0/15 pages [0KB], 65536KB chunk
unused devices: <none>
Is mdadm reporting this because there's only one spare for a RAID6? Or
is there something else I'm missing?
Below is my mdadm -D. Any suggestions would be helpful. Thanks!
