overflowError :int too large to convert to c long

[Parisa]

Dear all,

I'm running an event based hazard calculation by OQ 2.6

selecting 10000 ses_per_logic_tree_path leads to this error:

OverflowError: Python int too large to convert to C long



for smaller values I had no problem. since I have to perform larger risk analysis for next step, how can I fix the problem??

It would be useful if you could send us the files you are using. My gut suspicion is that this is a Windows-only issue.
