More info on periodic lockup problem with arla on linux 2.2.1/x86

[Neulinger, Nathan R.]

Ok. Have had the same two symptoms today - one with making a symlink in a
directory and having it not show up and the other with the afs access
locking up.

For the symlink, I was just linking: /home/local/adm/apache/websrch/logs to
./logs
in an AFS directory.

In the case of the lockup, when I turned on debugging, it looks like it was
spewing hundred of these to syslogs. Eventually it stopped (after I killed
the process that was trying to access the directory.)

There were two different sequences of debug entries getting sent to the
logs. A whole bunch of:

Feb 11 10:10:15 webindex arla[361]: Rec message: opcode = 10 (inactivenode),
siz
e = 32
Feb 11 10:10:15 webindex arla[361]: Rec message: opcode = 4 (getnode), size
= 29

Feb 11 10:10:15 webindex arla[361]: worker 0 waiting
Feb 11 10:10:15 webindex arla[361]: worker 0: processing

and then lots of:
