I guess the only way to avoid getting currently ongoing client crashing issue, it's best to restart eq2 after zoning or playing certain length of time to clear and release memory resource. Although I had time that client crashing even haven't zone for many times or not even playing for long time. That could be due to fragmentation of memory allocation, which probably only be fixed by flashing memory (which for many people means restart windows).
Hope they going to fix it soon...
