I'm trying to create an extract but I keep running into this error. I have a 105GB left on my disk and am running windows xp with 3.5gb of ram on a intel i5. I also looked through the log file and for some reason did not find it in there. I guess whats odd is that its only about 900k rows of data 50 columns wide which I wouldn't expect to be over 105GB. Could this be related to the virtual memory size? Its currently at 3.5GB for me.
Tableau Data Engine Error: 4: Not enough storage is available to process this command.
So for those that have had this issue and haven't been able to resolve it, I think I know why it was happening. I had some Keys in the Measures area and I think thats what was causing the issue. I moved them to the measures as they should be and that fixed the issue.
