Groovy Script Forcibly Killed. Elapsed time 47 seconds

I'm attempting to create a data source which runs a jdbc query using groovy scripting.

The query takes about 2 minutes to run.  

I have adjusted the collector timeout like this:

# script collector configuration
collector.script.enable=true
collector.script.threadpool=100
collector.script.timeout=360

I get the error : Groovy Script Forcibly Killed.  Elapsed time 47 seconds.

Is there some other setting or configuration that I need to adjust or is this a hard limitation for Groovy script, JDBC queries.
