Genetic Algorithm is no therad safe

What steps will reproduce the problem?
1. Start the first thread and make a Time Series Prediction
2. Start the second thread with the same dataset as first and it converges 
rapidly to the mean value

What is the expected output? What do you see instead?
An approximation of the curve similar to the first thread

What version of the product are you using?

2.2.4
Please provide any additional information below.
It is a web service with a multi thread prediction.
each thread makes its own prediction, but starting from thread n°2 the result 
is the mean value.

In the second thread I would expect an approximation of the curve similar to 
the first thread but instead I see a sequence of numbers very close to each 
other that oscillate around the mean value.
