I have not been able to determine exactly how the teachers are causing them.  I suspect that they are exiting rdesktop by just clicking on the X and not exiting the Windows TS correctly (because I can see Disconnected sessions in the TS manager).  Also, the teachers (and students) tend to exit almost every other application the same way: Just click on the X, or click on the upper left of a window and choose Close for the window operation, as opposed to choosing the applications File --> Exit.  This is a bad habit that I haven't been able to convince them to break since it works on Windows systems without obvious side-effects.  Each core file tends to be about 50-60MB and I have seen a teacher create more than 10 of them in a single day.  Eventually I will track it down, but for now I live with !

On a command line, try doing a:

file core.*

That will tell you what application is generating the core files.
