I have some Linux machines running kernel 2.4.19 with openafs.
(The machines are a mixture of Debian woody and potato, and
openafs is version 1.2.7 in all cases.
Recently I've seen a couple of machines with problems like this.
Here are log files from two AFS clients. They both had difficulties
at the same time on Sunday, when there is a cron job runnning.
What is the '-stat' parameter? For some reason I can't get into
the mailing list archives at the moment, so I can't confirm that
someone else asked something about this recently.
