Today I found 3 Wus errorring out in a row on my Linux host.
All showed this "signal 11" message in the stderr out.
Anyone has an idea?

PS: My Linux quad
All Wus didn't error out right at the beginning but after some minutes or even after 4 hours. :(

Hi Cori. ;-)

There can be several reasons for that, without any further notice in the log it could be hard to determine the reason.
There's another old thread with the same title created from me a long time ago and it appears in some other threads as well.
Maybe you find something which fits...

You mean This Thread ... :)

Very old thread indeed. ;-)

But since I'm not using any alpha BOINC client on that host I still have no idea what has happened. ;-(

Lovely greetings, Cori

Actually I posted that Thread because the Title of it was Process got signal 11 without really looking at it Cori. The Process 11 Error is usually a Write to Disk Error, nothing you can really do about it though.

If it happens a lot then it may be cause to look at your Hardware for some weakness or overheating ...

I'll observe that host then. ;-)
(It's pretty new but passively cooled so heat may be the only reason I could think of...
Although it's getting cold outside and the room has no additional heating turned on. *grin*)

Lovely greetings, Cori

Had the same on my quadcore (C2Q) box today, all WUs I had crashing within seconds and showing signal 11s. This box is new but it's totally Prime stable, is running five other BOINC projects without issues and temperatures were always okay. Since I have only just joined to this project, I have no idea why this is happening. I'm using a somewhat experimental BOINC client (from the Ubuntu repos), could that be the cause? I'm running 64 bit Linux but that should not be a problem, shouldn't it?

Thanks

Looks like the stock app isn't working.
Have you tried Crunch3rs application yet?

I've just done that and it doesn't seem to help.

I decided to try the optimized app proposed in this thread
http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=433
and it seems to work. Should be a bit faster, too. Hopefully all those flames about credit cheating and whatever found in that thread don't mean this is an app which will gain me unfair credit, cause that's not what I want. It's simply the only app I tried that doesn't crash on my system, for whatever reason.

Good to hear it's working!

Yes, it works fine, thanks a lot :-)
No cheating in sight, too... if anything, I seem to be underclaiming rather heavily.
