[OpenAFS-devel] OpenAFS on OpenMosix failure

[Terry Gliedt]

Upon returning from the holidays, I had a little present waiting for me. 
This time the failure has some map information.

Linux snowwhite.sph.umich.edu 2.4.27-om #2 SMP Wed Dec 1 09:20:51 EST 
2004 i686 i686 i386 GNU/Linux

This is:
   Fedora Core 1
   2.4.27 kernel
   patch-2.4.27-om-20041102.bz2 for OpenMosix
   OpenAFS 1.3.73

I expect the machine was lightly loaded, given when this occurred. 
Anything you can suggest would be appreciated. This is not the only time 
this sort of thing has happened.  TIA
