Something is off. Firstly, BOINC should always give a reason when it suspends automatically. Second, it resumed twice in a row (although maybe there is a gap from when you copied it).

So. Why is it suspending? There are many possible reasons. Insufficient memory, suspending when the computer is in use, suspending when the computer *isn't* in use - it gets complicated.

To help us get to the root of the problem, please will you check your active preferences? Copy the contents of global_prefs.xml, and (if it exists) global_prefs_override.xml. You will find both in the BOINC folder.

Thank you.

Hello,

</global_preferences>

Looking at this, I wonder if this line doesn't cause the problem:
<suspend_if_no_recent_input>20.0</suspend_if_no_recent_input>

Finally, I'm running BOINC on 4 different PCs (3 desktops and 1 laptop) and the problem is the same everywhere. Also worth mentioning I'm running the French version of the agent?

Thanks for your help, ALLP
