High memory consumption per Switchyard deployment

Solution In Progress - Updated -

Issue

We have a problem related to the memory consumed by the Switchyard/Camel applications deployed in Fuse 6.2.1. We took some measures on memory consumption and the growth seems linear:

No Services Deployed      > around 65 MB
1 HelloWorld Service      > around 77 MB
10 HelloWorld Services    > around 87 MB
100 HelloWorld Services   > around 350 MB
150 HelloWorld Services   > around 560 MB 

What can be done to reduce the memory footprint with a high number of deployed Switchyard/Camel applications?
