so maybe it is this one you need?

Hello, Here is the varac log, with manually added marks between crashes

Hello, I think that the VarAC log file is this one. As you can see there are some days, and the error occured many times I have add a mark before each relaunch

Thanks for the answer. I can send you 3 files : - The screen copy of the error message - the details of the error - and when i launch back after the error, i have to launch 2 times, because the 1st ends with an error. In the 3rd file, you have the text of the 1st and 2nd relaunch in the linux screen Hope it's enough for you. Many thanks
