[OpenAFS] Gentoo amd64: Each process attempting to access a certain directory is blocked

[Hans-Gunther Borrmann]

Hello all,

what I did:

cd ~   # my home in AFS
tar -cvf tars/tar.tar .backup   # .backup mountpoint of backup volume

After some time the tar hangs. Therafter each process attempting to acces the 
directory ~/tar hangs. It is impossible to terminate the processes in any 
way. In the meantime the directory is normally accessible from other 
AFS-clients. Only a reboot resolves the problem. 

This makes in fact one of our webservers unusable, because the same  happens 
with directories php-scripts access. In a short time several hundred scripts 
are hanging around and the whole server stops service until it is rebooted.

I am running OpenAFS 1.3.85 since several months very successfully on the same 
hardware under 
Portage 2.0.53 (default-linux/amd64/2004.3, gcc-3.4.3, 
glibc-2.3.4.20041102-r1, 2.
