MaxSpotInstanceCountExceeded when max spots should not have been exceeded

[TristanTrim]

I just signed up with aws. My spot limit for c1.xlarge seems to be 20, but brenda is getting a MaxSpotInstanceCountExceeded back from amazon.
I have one spot running and it is the only one I've managed to start. Anyone know what could be happening?

trist@bizmuth:~$ brenda-run -P -i c1.xlarge -N 1 -p 0.15 spot

Were you able to figure this out? I am having the same issue.

Yes, I requested an increase in spot instance requests from amazon. That did the trick.
