I got a "micro" instance to play with last week, and I was able to start 9
instances of AjaxExample from Wonder. The server was only running httpd,
JavaMonitor, wotaskd and the instances. After 9 instances, wotaskd was still
trying to launch the other 21 other instances (I wanted to see how the VM would
react) over and over again.

Look like that error is when the system is out of memory. Run the "free"
command to check how much memory is available:
[probert@wocommunity ~]$ free
total used free shared buffers cached
Mem: 1574912 1564208 10704 0 22528 646312
I did notice that a "micro" instance don't have any swap space, which is kind
of bad. If you can live with a bit less of disk space, see :

Maybe the other instances size have swap space by default, but I don't know.
