Is this behaviour normal? Sort of. Some fancy parts of X like file-manager/exporer applications tend to call fstat() a lot, but it's probably tunable, and if you enable NFS attribute caching that will help a lot. "ls /afs", if available, is a wonderful test of whether a program/file-manager is being polite. Anyway, "top -mio" is likely to be informative. -- -Chuck
