I don't remember seeing that "CIMCPU" script before. Is it an add-on
from somewhere? I'd guess that there is probably a "DEBUG" flag for
extra logging output that has been left on. In any case, it does not
look connected with the other problem.

The thing that I noticed is that the files which Larrd is trying to
create look weird. Their format should be similar to:

  host.domain.com.disk,usr,local.rrd

This is the name of the host (FQDN) followed by the word "disk" and
dot separated. Then should come the mount point for the filesystem,
but comma (rather than slash) separated and ending with ".rrd".

In your case, I see two (possibly related) symptoms. First, the
mount point section is not having the comma substitution performed.
As a result, Larrd is trying to create files in a (probably non-
existent) sub-directory. Secondly, the mount point paths look odd.
"/dev/vx/dsk/tradearcdg/vol12" looks more like a logical volume
device rather than a mount point.

In order to investigate further, it would be helpful to know
what OS the machine "user.trade.triton.ahrend.net" is running
and something about how the local disks are organised. It
would also be useful to see what the format of the BB "disk"
test for this host looks like.

My guess would be that the output of "df" on this particular
machine is not what BB expects and the format is causing
Larrd to become confused.

Cheers, Phil.
