New Todo: Out of memory errors



During odd hours i get spammed by various sensors.


There is something that you need to pay attention to:
ToDo: Data
Subject: Out of memory
Error reading historic data (Device=11300 Sensor=12283 Date=14/11/2010) Error: Out of memory

The sensor ID always changes but its regarding the same error.

What conditions does this happen?

I have PRTG installed on a Windows 2003 Server@32bit with 4Gb of memory and it doesn't seem to reach the memory limits.
