Hi,
I have detached your project on all my computers cause when I start BOINC he start directly your exe who fill my memory (16 GB).
The PC become freezed...Only way is to restart with power button or to wait a long very very long time to kill the task...if u can...

I do 3 hours to make BOINC detach the project and stop calculate on 2 PCs.
2 PCS with windows 7 64bit all updated

Do you get this errors to ? I'm a bit afraid to test again now.

Thanks !

I forget to say that in my configuration BOINC can use only 40% of memory when the PC is used and 80% when idle.

And 75% usage of CPU (but that not look like a CPU problem, just the memory, the I imagine the page file...)

I have noticed that multiple occurrences of the program are in memory taking 1-2 GB of main memory when Boinc shows only one as running and another one waiting to run. The paging rate just skyrockets. I suspect this happens when Boinc decides to switch tasks.

My app.config looks like:
<app_config>
<project_max_concurrent>1</project_max_concurrent>
</app_config>

You might want to suggest this to users to prevent multiple tasks running concurrently.

The problem with old version was that each copy of the program running took up about 2 gigabytes of RAM, given the size of primes that are being checked. Now each copy takes up 1 gigabyte. To check a prime near 250 million, the program has to create an array with 250 million entries. On my computer, using an app.config file does not seem to be necessary with the newer version because BOINC automatically limits the number of versions running.
