Hi,

this is a problem I have since several years now: boinc works fine for hours, days or even weeks without pause. However, when I put one or more of my hard drives under heavy load, the running boinc processes get into problems. It looks like the boinc processes try to access the hard drive, but run into some sort of timeout, eventually resulting in a SIGSEGV. This renders the current progress invalid. But even worse: boinc now launches new processes that are accessing the hard drive much more, which also fail. However, this is still not the peak of tragedy: with four instances of the "clean energy project" from the world community grid, the load on the disk drive is high enough to keep itself in this timeout loop, even when all other disk access has stopped. This renders my computer almost to 100% unresponsive for about 10 minutes. After that, each of the remaining tasks in the queue has started and crashed after some seconds.

When system is idle again, I can re-fill the task queue and everything works fine again.

Any ideas what is going on or how this can be fixed? (By me or by world community grid or by boinc?)

My system configuration:
mainboard: ASUS P5Q-EM (Intel G45 chipset with Intel GMA X4500HD)
cpu: Q8400s (Intel Core2, 4 cores)
RAM: 8 GiB (4x 2 GiB, dual channel)
operating system: Gentoo Linux (profile default/linux/amd64/10.0/desktop/kde)
boinc version: 6.12.42 (account from world community grid)

If you've been suffering this problem for several years that would cover many versions of boinc - initial thoughts are that this is a hardware (or local) issue. First thing I would check would be the power supply.

CIC1=CC=C(C2=N[C@@H](CC(OC(C)(C)C)=O)C3=NN=C(C)N3C4=C2C(C)=C(C)S4)C=C1

Only thing I could suggest would be to hemebrew a kind of a monitor what would watch for such disaster. However, the brewing itself should take place in more appropriate fora (whatever scripting language you prefer). I assume, that switching for less intolerant project is not an option.

I'm counting for science,
points just make me sick.

Power supply is probably ok. I replaced the unit about one year ago.

Actually it is. This has been my workaround since the beginning. However, sometimes I give it a try again, hoping that it will work without the problem.
