I logged onto s400 and took a quick look.  After noting that the LDM
was running, I checked to see if it was receiving any data:

<as 'ldm'>
cd /cutrim1/ldm
ldmadmin watch

I saw no data being received.  The most likely cause of this situation
is a corrupted queue.  Given this, I did the following:

ldmadmin stop
ldmadmin delqueue
ldmadmin mkqueue -f
ldmadmin start

The LDM started nicely, and data started rolling in.

So, I think that the problem was that the queue got corrupted somehow
and data stopped being received.

Hi,

Thanks once again. Will keep this in mind ( about the queue getting 
corrupted ).
