SPSS hard limits are about 2.1 billion cases (2**31 cases) and about 2.1
However, your computing environment probably causes much lower limits.
What OS are you on?
How much free disk space do you have? How long since you did a disk
check and defragmentation?
How big is the .sav input file?
the uncompressed scratch data file should be about 35000*300*8 bytes =
84,000,000 bytes. Even for sorting you shouldn't need more than about
3*84000000 bytes = or 252M.
Are you creating a lot of files?
If you are doing several procedures do some of them work, and then you
get the error or do you get the error immediately?
Does just a
Get File . . .
execute . . .
have the problem?
What exact error messages are you getting? (should be in .spo and .jnl
Are you running standalone or from a server? for the data? for SPSS itself?
Does you OS allow you to see if you are running virtual?
