I have 3 mac labs to take care of here at this school. All 3 are for graphic design. They all use photoshop. About once a month a students photoshop file becomes corrupt. They work long and hard on these files and when their files become corrupt they are very unhappy with computers. So all three labs connect to the same server to save their work. The server is an x serve. I maxed out the ram in the server to 8 gb. The cpu does not go above 50% usage since i put in the new ram. Before the ram iwas maxing out the cpu. The students use the white g5 macs. All their work gets saved to the server and not on the local computer. Is there some detail or something that would cause this. The teacher tells me that photoshop tells trhe student that the file is empty when they try to open it.
