Thanks
Checked "Computing allowed -> while computer is in use" in preferences.
It will probably make a difference. I´ll also try to pay attention to the checkpoints, as mentioned.

There's a screenshot of the WCG Device Profile in the FAQs accessible 24/7 :D

Think but cant confirm this moment that BOINC is designed not to unload an application before the first checkpoint? No one ever notices with RICE and DDDT because of the very short intervals but with the other 3 projects it is a serious matter.

Certainly the design is to not let it do a project switch before the first checkpoint is reached. Else there is a chance that there would never be progress particularly when "Leave application in memory while preempted" (LIM) is not on and the setting is unselected for "while computes is in use".

Anyway, I just tried is and re-confirmed: Unloads apps when LIM is Off and Idle/Resume is used. 4 jobs on the quad just returned to last checkpoint and did went back a good hour in progress on a FAAH job

Think I've lamented this design before and in 6.2.28 it still does so, but Didactylos did comment something like: "behavior exactly as the field description says".

Note to Self: The Checkpoint FAQ needs a paragraph on LIM but distinctly remember a Frenchman promising a whole separate FAQ for this topic so I can do with just a x-ref

I had the same problem over a month ago, except with me, the agent would stop running without my doing, and when I restarted the agent, the progress would start at 0 again. It happened a few times, It was a configuration problem for me. I had to add something to the file (I'm not a programmer by any means).

If you look at the thread "Strange faah4454 behavior", you'll see what was happening to me,, and how it seems to have been fixed. So far, no problems.
