We actually experienced something similar when we started to run IDL
on an SGI Origin 2000 machine. But in our case, it was definitively NFS,
because you could also copy files with some other machine on their hard
drives, and the SGI wouldn't catch up (which caused me run over quota a
couplke of times although I had deleted files). Our sys admin somehow
managed to fix this.
Short message: Try to find a test that is independent of IDL, then you
know at least who is to blame (and who should fix this).
Martin.
