[OpenAFS] Users having problems getting into their home directories

[Madhusudan Singh]

Hi

I deployed an openafs server on Debian Linux about 4 months ago. It has a 
backup process defined under AFS that creates backups at 0100 hrs. It has 
been up ever since. However, starting this morning, users can no longer get 
into their volumes. I have rebooted and restarted openafs-client services, 
but to no avail.

(why are there two afsd processes running ?)
