Hi Daryl,

Thanks for the info.  We'll stash it in the archives for others who
might try to do something similar, although the kernal trace got mangled
in transmission...

We have the LDM running successfully on both RH7.0 and 7.1 machines -
nothing like what you've shown us here, but then none of them are
blended systems like you've got. 

Anne
