[OpenAFS] Request for Assistance with OpenAFS

[stefania spagnolo]

Hello all,

on my mac (10.5.8) , where I'm  using very frequently OPENafs I  
suddenly got this error message when trying to restart afs after  
resuming the macbook after sleeping:

  sudo /Library/StartupItems/OpenAFS/OpenAFS start
Starting OpenAFS
Loading AFS kernel extensions
kextload: extension /var/db/openafs/etc/afs.kext is already loaded
/afs does not exist. Not starting AFS client.

any hint on what can be the problem ?
Many thanks for any help.
