Without knowing anything else, I am going to guess that the answer is 
you misprogrammed some concurrency code--on the desktop, contacting the 
database on itself is likely to cause some caches to end up being 
flushed and thereby causing memory to become updated across threads, 
while a database on the server is not going to cause remote cache flushes.

This I can't answer without knowing anything else. Concurrency could 
again be a fault here, but I really don't know.

SSCCE would be invaluable if possible. To beat a horse to a bloody 
death, if all other explanations fail, concurrency can be a good guess 
for failure, but that does imply that most of the other code is not 
buggy in this sense. In any case, I'm not entirely sure what you're 
doing or what the correct outputs of those actions should have been, let 
alone where in the code it could be failing.
