You could take a look at Dynsize: increase it by a factor of 1.5
    for instance.

Also look at Maxusers: never make this parameter too high, to
    accomodate some 80 students, I expect that 40 to 50 is enough.

And check Max_procs (lower it to something reasonable).

At a site in Holland there were similar problems, which
disappeared after changing:

      Maxusers (from 100 to 50)
      Max_procs (from 50 to 30)
      Dynsize (from 524288 to 750000)

At that time (they have upgrade their system with XPC's later),
their system was about half the size of your system, but their
usage (also mostly students) was more than half of yours.
