David,
zip format files for 32bit WindowsXP maxes out at 4GB. You can
create larger zip files on Vista. I'm wildly guessing that you are
running into the 4GB limit as well on reading your zip files with . 7zip,
http://www.7-zip.org/, might be able to handle zip format files larger
than 4GB. If that doesn't work, see if you can switch to gzip format.
Gzip works just fine with files larger than 4 GB on 32 bit Windows systems.

Re: [gdal-dev] Shortening execution
09/19/2009 01:16 time of Python script
AM
So the problem is that ArcGIS Server is expecting the data to be ready
(unzipped), but due to the large size of the data set, the unzip has not
finished?

I have a Python script that automatically downloads zip files containing
large datasets from another server and then unzips the files to further
process the data.
It has been used as a geoprocessor of ArcGIS Server.
The script works fine when two datasets each has several kilobytes size,
but the script stops half way when datasets were about 11,000KBytes.
I think that the execution time is too long and ArcGIS Server just simply
killed the process.
What actions can I try to reduce the execution time?
ArcGIS Server only works on the basis of 32 bits and I was told that the
maximum memory it can utilise is 4 MBytes.
I should be grateful if someone can make suggestions/recommendations.
Sincerely,
David
