Guess you're right, James. We did have crashes, and these occured either under Wine or Firefox e. g. with some strange French or Canadian student websites using a lot of Java and graphics. Not all of our terminals seem to have 512 MB as I thought, but I found some of them with even less than 256 or 128 MB... but not all! Of course, I don't remember at which terminal the crashes appeared. When I heared people sighing "mine has crashed again", I checked for ltspswapd and found it off (why soever). Switching it on removed all complaints, i. e. I didn't hear anything since then. So it seems to matter for us. But I have it on 512 MB per station, not 1024. So if you think a terminal with 512 MB RAM on its own would never ever need swapspace, I could save a lot of disc space and network overhead. But when I look into the swapfiles, I can see that all of them are frequently used and e. g. contain rests of data from Firefox & Co. Even on 512 MB machines.
