Multiple Instances of IndigoPluginHost

In reviewing my cpu usage in Activity Monitor on my Mac Mini Server, I see that some 15 instances of IndigoPluginHost are all currently running. Is that normal? Is there a separate instance for each active plugin? I have been having problems with one plugin sometimes running away with near total cpu usage, so I am trying to track down the cause.

Yes, each plugin runs in its own sandbox (for stability and security). If you know the process ID of the plugin using lots of CPU, then from the Terminal you can do:

ps -axww | grep IndigoPluginHost

and find it (notice towards the end will be the plugin file name).
