We've put AV3.3 on some 64-bit machines, including Spatial Analyst and Image Analysis. I have used it quite a bit, and it seems to work overall, but now that I'm really digging in, I'm starting to have trouble with certain processing tasks.
When I do a Union on two large but not huge polygon shapefiles it gets to 13% done on the 'first pass' and hangs -- CPU bounces between 3 and 11%, and the memory freezes in the neighborhood of 20-25Mb (two different tries processes froze at different levels). An Intersect worked fine on the same two datasets using the geoprocessing wizard, but within a well-established, never-been-a-problem script it hangs -- but at different points. The status bar goes to 100%, the info says Querying subwta.dbf.... I also tried to Clip, again from the geoprocessing wizard, and it seems to be hanging on Splitting Shapes. On shpae 1 of 4998. CPU is bouncing in the mid-high single digits, and the memory hasn't changed in several minutes.
So, I can't say I've done all these tasks before on this install before, but I can't say I haven't either. I'm in information-collecting mode. Has anyone else had problems like this? Any idea where to start looking?
Thanks.
