Access is on the "Memory leak blacklist" which can be found here:

I don't pretend to understand this phenomenon, but your symptoms fit their
description perfectly.
**********************************************************************
The problem is that as the user works in Access (entering data to a form
and saving it to the network database), system resources gradually drop off
and eventually a message pops up that the machine is short on memory. When
I check system resources, I find that they are at 2%(!!?). Killing Access
frees nothing, and a reboot is the only alternative. Then the process
starts again.
