Problem with ocean script

Hi, 

I'm using ocean script to run Monte Carlo Simulation. Everything is fine when the start iteration index (MonteCarlo parameter: ?startIter) is smaller than 1M. 

However, when ?startIter becomes larger than 1M, I found the Monte Carlo output is not able to be printed to the csv file.

Below gives an example:

I start 10 Monte Carlo simulation with ?startIter = 1000001. Ideally, the output csv file should have corresponding 10 Monte Carlo simulation results from iteration 100001 to iteration 100010. 

It shows that the monte carlo runs successfully in the terminal, e.g. 

However, in the output csv file, iteration 1000001 to iteration 1000009 are missing, only shows 1000000 ( actually is not wanted) and 1000010:

=======================================

In my oceanScript, the "output to file" command is:

ocnPrint(?output fp value(VT("/out") 5e-09) ?precision 10 ?numberNotation 'none)

Can anyone help me to find where is the problem? 

Thank you in advance!
