I got even worser today. This server provides nfs3 mounted home directories
for a small network, but working with OpenOffice is unpossible. Loading a
file looks fine, it get displayed properly, but then it hangs, before being
able to do anything. Killing removes the process. Reverting to 
2.6.18.something on the server fixed both issues. Client and server are 
openSUSE 10.2 installations.

As it stands, 2.6.24-rc8 isn't usable for me at the moment. Let me know, if
I can provide more details for these issues.

Here's the OpenOffice call trace:
