>>In order to solve some issues I had encountered, I am using SYS(3050) to adjust the memory settings. I am saving the old settings, setting the foreground and background to 64*1024*1024, running my query, and putting the settings back. One client is getting an error when putting the settings back. It seems that the original foreground setting was -1351876608 and setting it back to this value causes an error. Why is this causing an error? Do I need to put the settings back?

The original setting was actually a NEGATIVE 1351876608. Why would this be? What does it mean?
