Streaming stopped itself ?

Hello again,
I am always on my development for X3-10M.
I 've adapted a program from Snap ApplicationIo Class.
It is a console application.
My application is working well getting data from an external trigger.
2500 samples for 4 channels with a trigger at 20 Hz or 40 Hz.
My application is working for 3-4 hours and after that I get no more data.
I tried to detect this behaviour to relaunch the streaming by stopping it and starting it again but it doesn't work again. I have to close the program and launch it again.
Do you know why the streaming could stop after 3-4 hours ? ( AutoStop is at false)
Thanks for your help
Best regards

Some PC systems implement power saving modes that disable the PCI Express interface after some hours in an effort to conserve energy. Be sure to disable all such modes in the BIOS and in the operating system. This is the most likely culprit.
