I keep getting this error and my client will continue looping until I delete the WU and another gets assigned.

If you're running this in a VM and have 512 MB or less dedicated to the VM and accepted the default swap space in the guest OS (Ubuntu 7.10 anyway), you'll lose the WU with the error you report.

Two questions :

- how many RAM do you have (and that the client can use) ?
- what's your CPU ?

All reports I have seen about this error have showed a problem with the WU and nothing else; client, memory assignment or anything like that. I think your time will be better spent working on another WU, but don't take my word for it. Hopefully a more knowledgeable mind will enlighten us.

there has been talk about this Wu in another thread; it's definately a memory hog. I have 3 of the 2619's running now
all on C2D E6400 with 2 Gig. mem. All are showing memory usage around 956 meg. Counting additional overhead
I doubt you'll get a successful completion with anything less than 1 gig. dedicated to the client.

Yes I'm running it on VM but in the client I've indicated only 500MB free of RAM so why am I still getting assigned this WU.

And since I've only got 2GB of RAM I'm not about to assign 1GB just for the VM.

CPU: E8200 @ 3.2GHz
RAM: 512MB
OS: Ubuntu 7.10

I really don't see the point in running a VM on a dual core ...
