Hi all,
i had a lot of this error during this past week.

I don't know to solve this problem.
Thanks for your help in advance.

p.s. I didn't modify anything, and the next WU is working normally.

Hi and thanks,
in this computer, with quad core, i have Boinc with 75% core utilization (3 core for Rosetta@home and 1 core for 2 Nvidia GTS 450 running Gpugrid), running H24.
I don't have problem with memory (always there are about 400 KB free and, i think, no paging activity).
Windows 7 is x86.
The global cpu utilization is always around 80%.
Tell me if you need other informations.
Thanks in advance.
k.

You might want to check the properties of the Rosetta@home tasks. I think the memory usage varies throughout the run, and can get quite big.

- It's over 435MB Virtual and 440MB working set 1min into a run, for each task! That means >=1.3GB of your 2GB is being used by Rosetta alone.
Each GPUGrid tasks requires around 120MB working set/150MB Virtual.
That's over 1.5GB for the Boinc tasks.
W7 requires 1GB minimum, and then there are other apps including Boinc Manager to consider.
I expect Windows is writing to disk a lot. This can cause heartbeat failures.
Then there is the screen-saver/pop-up bug impacting Rosetta, and Ralph.

- 5min into a run and each Rosetta tasks memory requirement rose to 518MB. So I think that's the source of your problem. Consider a CPU project with low memory requirements such as fightmalaria@home.
