[Linux-cluster] GFS load average and locking

[Treece, Britt]

Wendy,

The ticket number is 836516.  We've been told that it has been escalated
to the GFS engineers.

Here is lockdump information that we've pulled on an inode whose httpd
process is in the "D" state...

$ sudo lsof /data02 | grep 14060
httpd   14060 nobody  cwd    DIR 254,66  3864 93725927
/data02/resources/htdocs/SVVS-2006-03-02-06-17-20

/data02/sessions/6/c/2/4/sess_6c249351c42e2c19c669b068433db9a8

$ ps -auxwww | grep 14060
