Have you tried increasing the 
supervisor.slots.ports ?I suspect you are getting limited by it. - Roshan

Hi everyone,

I developed a prototype of a platform that uses Apache Storm behinds the scenes. My platform's
"developer mode", which is currently the only one supported, uses Storm in its local mode.

For small applications, that only had up to ~3 simple topologies, this worked great. However,
for slightly larger systems (~5 topologies) I find that some of the topologies are not executed.
I suspect that the local cluster is configured with a small number of executors, so when the
number of bolts and spouts I'm using (with p=1) exceeds the number of executors, no further
topologies are scheduled.

I know the "real" solution to this problem is to use a real cluster, but using local mode
is very convenient for development.

Is there a config I can set to tune up the number of executors (or alternatively, is my understanding
of the problem correct)?
