[LDM #RCK-299610]: can't run LDM

Hi Karen,

The fact that the installation is new but with a previously-existing 
product-queue makes me suspect that the previous LDM installation didn't 
support large files and the new one does (by default).  The product-queues of 
the two build-variants are incompatible.

What does the following command output?

    pqcheck -v

If it indicates a fault with the product-queue, then your choices are:

    1.  Remove the product-queue (ldmadmin delqueue) and recreate it (ldmadmin 
mkqueue -f); or

    2.  Revert back to the previous LDM installation; or

    3.  Rebuild and reinstall the new LDM but without support for a large 
product-queue (./configure --disable-max-size).

I recommend #1 if you can afford to recreate the product-queue (by default, it 
will become populated with the last hours worth of data).

Let me know.
