Hai everybody,
----------------------------------------i posted some months ago about random errors from different WUs from WCG. Cause of this errors i checked the hole machine, got all timings and settings on the standard/normal level - hardware is in the signature. Today, i got an error (and the time to hunt it down) again from MCM: MCM1_ 0007100_ 9182_ 0-- <core_client_version>7.2.42</core_client_version> I cannot see, why this WU got an error (maybe, cause i started an VM???) This also causes, that my virtual machines start, but i have graphical errors and it is a MUST to reboot the physical machine! Any help will be appreciated. Thanks in advance LAZA

As i see now, i got another one the day before:

Reference to this faq on signal 8 http://boincfaq.mundayweb.com/index.php?view=377 , which it says to have occurred in the log, may have been posted before. Finds on these forums of this error are, ahum, extremely rare. You mention a VM environment and a parallel simultaneous crash of a fahv task. What does that one say in the result log and the message/event log (data stored in the stdoutdae.txt/.old files). Was the VM encroaching on memory, pushing other processes aside?

And a find at another project, ut chemistry, http://theory.cm.utexas.edu/forum/viewtopic.php?f=9&t=1503
Whatever the meaning is, maybe it can interest armstrdj or seippel. |

The answer on the problem there is: "The signal 8 error means " SIGFPE 8 Core Floating point exception" and is project-related. I have edited my input parameters handle this error and have not had such an error has not occurred since." And i'm not crunching on this project anymore (also, there is an successor ;-) Edith: I crawled a bit through my system and found this:

Finds on these forums of this error are, ahum, extremely rare. Maybe, cause the BOINC FAQ Service addresses only "and your operating system is Linux with a Kernel version of between 2.6.20 and 2.6.27, then read on." You mention a VM environment and a parallel simultaneous crash of a fahv task. What does that one say in the result log and the message/event log (data stored in the stdoutdae.txt/.old files). Was the VM encroaching on memory, pushing other processes aside? Maybe this happened, but the kernel should stop/pause the WU if the VM needs RAM, CPU time, ... (in an ideal world).

LAZA74, Signal 8 is Floating Point exception. In general this could be an application problem or a problem with the specific computer. In this case since other copies of same work unit completed successfully on other computers, that would indicate a problem with this specific computer. As a starting point, I'd suggest hardware checks. Also, keep in mind that a computer with WCG installed is being utilized to a much larger extent than a normal computer, so hardware problems that might otherwise go unnoticed are more likely to show up.

Thanks Seippel for your advice.
----------------------------------------I did a check (RAM) some months ago as i had the problems for the first time. I also set all settings (BIOS) back to "normal" or "standard" so that OC and other side effect things can be barred. I attached a SSD and doubled the space for the root partition cause of some WUs needed more space. These machine is crunching for years so for me it is a problem with some(!) WUs from MCM - or a bad side effect from a other WU like FAAH (where i get errors and posted also). Seems, that i have to live with it and hope, that this sort of WUs is running out...

You may have an overheating problem. Since you have been crunching a long time, when was the last time you cleaned or blew out your heatsinks ? Cheers

Cheers The Sensor-plugin is running and shows not even 60°C (= 140 Fahrenheit). I crunch only with 3 Cores, so the system load is roundabout 80% (with some other programs running also!) I think, that it is not a (over)heating problem... Cheers
