P3 Project Manager Crashing with EBDClient error, when refreshing (F5)

Question

My company has 3 sql databases for Prima on a server; 2 are approximately 1.5GB, and the third is just over 2GB
We have 5 client machines (xp sp3 32bit), that use the following setup:
P3 Project Manager version 5 (no service packs installed, but have tried sp1-3 on my machine with the same error)
oracle client 9.2 with tnsnames pointing to the sql server with the prima databases
each machine has 2GB memory with a 3-4GB pagefile
I do not have issues refreshing the other smaller databases.
both the client and server do not take a significant hit on resources while refreshing.
both the server and client are not reporting any errors under event viewer.
they all receive the following error when refreshing (F5) while logged in the third and largest database:
