Hey guys!

Maybe you can provide some insight. I'm getting a lot of these today, wasn't happening yesterday - not that I saw.

I'm getting several tasks that are returning with computational errors citing this line:

(unknown error) - exit code -1073741819 (0xc0000005)


Anyone have any clue what is causing it and how I can try to rectify it? It's really bugging me.

I've suspended the processing until I get this sorted, an example task is this one: http://www.primegrid.com/result.php?resultid=472958504

Edit:

Additional noted of relevance.

My CPU isn't running hot, its nice and cool actually. It also isn't over taxed, I'm using only half the capacity for these tasks.

This also doesn't seem to happen to every one of the tasks, just enough to get my attention. This baffles me even more, if it were an issue every time I'd have had more of an idea what was wrong.

A quick Google search suggests you should download a memory testing program and run it.

I'm not sure why I didn't think of that.

Looks like one of the memory modules in the computer is faulty, I'm getting sent a replacement.

Thanks for pointing that out. I'd have been here scratching my head for ages otherwise!
