blocked remote subdirectories

["Tradebit Service" <info@tradebit.com>]

hi everybody,

for a few days now i run a new setup
with NFS on RHEL4 (kmountd nfs-utils 1.0.6) and
from our storage I serve a few hundred thousand
files of all sizes to 3 other servers.

now, in these (around 14) days, I had 5 incidents of
blocked subdirectories on the server from different clients.

2 times the directory "came back" after a few minutes 
(have seen that mail too late) and in the 3 other cases,
it did not (maybe I was too fast).

for the time the dir is blocked, the failure looks
like a rights mismanagement, but nothing changed it just
denies access for minutes/hours.

the directories were deep in the dir tree, but random as
it seems.

does anyone know, how to prevent that in the future?
what could be the cause of these voodoo incidents?

any help appreciated,

thx,
Ralf Schwoebel
