ohBOYwhatfunwearehavingnow?!

Here's the setup.

Got a system running in VFP 3.0 under Win 3.x on 486's and 586's w/16Meg ram on Novell 3.x/4.01 networks. The system .EXE resides on the home network of the different areas using it. Using GPnet calls, it attaches them to a Novell 4.x Network for the actual work and then detattaches/logs out when the user hits 'Quit'.

Buffering on all changable files is set to '5'.

Here's the problem.

In the Data Environment I set up all of the relationships for the files to the main file. Apparently, when a relationship exists, and the child file does not have a corresponding record, it creates a 'phantom' record in the table which (apparently) is quite real to Fox. But since the tables are all buffered, this shouldn't be a problem, right? Or am I completely misunderstanding this whole concept of buffering?

Anyway, quite a few of the 486's are running extremely low on system resources and when this happens we start to see system-wide problems. Mostly it seems that all of the systems are trying to get the same 'phantom' record in the main (network) file. Why?

Has anyone else run across this type of problem?
