Hi,
OpenOffice hangs on NFS when I try to save a file or even when I try to =20
open the save dialog in this case.

It is not possible to exit or kill soffice.bin. I had a slighty different=
=20
procstat stack before, but that was fixed a couple of days ago.
Any thoughts? Enabling local locks in NFS doesn't fix it.
The nfs server is an up-to-date Linux Debian 5 with kernel 2.6.26.
If more info is needed. I can easily reproduce this.
Ronald.
