Hi Aswin,

I am not sure what is your question.
To me, the segment definition in your example below seems incorrect.
You should not include in a spread configuration file unless
the configuration file includes exactly one segment with exactly one

Having said that, I don't think this relates in any way to the problem
you have with partitioning.
