Hello all,

Sorry for picking this up after such a long time...

The system is running 11.1 meanwhile, and has the fixes mentioned above (I
just checked this again). However, an unavailable nfs server (some
directories simply mounted under /net) still makes it hang on this command
(from ps aux):

---
root  51860   0.0  0.0   8364  2672  -  D    00:07         0:00.24 find
-sx / /dev/null ( ! -fstype local ) -prune -o -type f ( ( ! -perm +010
-and -perm +001 ) -or ( ! -perm +020 -and -perm +002 ) -or ( ! -perm +040
-and -perm +004 ) ) -exec ls -liTd {} +
---

Any ideas why this happens (and how to prevent it)?
