If the data can be processed without error after the XP is rebooted, and 
this only happens after many days of use and not at the same spot in the 
data or programming, it seems unlikely that it is filePro, however, here 
are some things I learned.

If you have variables that are undefined, using aa instead of aa(8,.0) 
for example.  Each record that needs to assign a value to aa will use a 
new memory location.  So eventually you will exceed the memory 
available.  This is noticed on a report where it crashes at about the 
same number of records but not a specific record.  Or a long data entry 
session that is never closed and does this kind of thing.

This is more likely to be the case with Windows98 because of differences 
in the Operating system that had memory leaks that could not be plugged 
and resources could easily be overtaxed.

I would never use an XP client to a Win98 server.  I don;t thing this 
should even work.  We had all kinds of issues when I had a few customers 
try that.  Always use the newest OS for the server, it will be able to 
handle the slower clients but I can't imagine the Win98 being able to 
handle the XP client well.

Well I don;t know if that helps but good luck.  Reboot the server and 
client frequently  to reset all the memory issues and see if that helps.

Crazy solution but it is Windows - what else can you expect.
