That is from 2001, which was over 7 years ago and a different openafs 
version.  The 1.4.x series seems to have much better stability than the 
1.2.x and older versions (the mentioned 3.4a version is from 
Transarc/IBM and predates openafs.)

I have it turned off and have not had problems:

% bos getrestart localhost
Server localhost restarts never
Server localhost restarts for new binaries never
% uptime
 up 611 days

This is with openafs 1.4.2 and stability likely improved in newer 
openafs versions.


At a minimum though, you should set each of your different AFS servers 
to restart at a different time.  You do not want them all to restart at 
once and have your cell go down.
