Out of memory errors

Hi All-

I've been playing steadily since September with no problems. In the last month or so I've been getting errors, seemingly at random. I can play for five minutes or an hour, and without warning will get a Windows pop up error message. Again, this is a Windows error message, not GW:

out of memory Array.cpp(88)
out of memory exefile.cpp(10)

This is two different error messages, by the way. Ususally I will get one or the other. This morning I got both error simultaneously. Once I receive the error I crash to desktop. This happens almost anywhere-in towns, instances, you name it. It's starting to really piss me (and my guildies) off.

System Specs:
P4 3.2 gHz
GeForce 6800 GT
1 GB Ram
XP-home version
Direct X 9c

Any more information you need please let me know. Thanks in advance for the assistance.
