Version 5.0.6 of the LDM is quite old.  If your product-queue is filling-up 
rapidly, then that's  likely due to reception of more data (since the 
introduction of LDM 6, there's been a steady increase in the amount of data 
flowing on the IDD).  It's likely that an LDM 5 will have problems keeping up 
with the flow.

Upgrading your LDM would be my stongest suggestion.

Upgrading is pretty simple (we have it down to less than three minutes :-).  Go 
to the LDM home page <http://www.unidata.ucar.edu/software/ldm/>, click on the 
latest version, then click on the "LDM Basics" link, and then follow the 
instructions under "Installing, Configuring, and Activating the LDM System".

Assuming you have a standard installation, then the steps should be something 
like this

    $ cd
    $ zcat ldm-6.4.5.tar.Z | tar -xf -
    $ rm ldm-6.4.5.tar.Z
    $ cd ldm-6.4.5/src
    $ ./configure >configure.log 2>&1 &&
    make >make.log 2>&1 &&
    make install >install.log 2>&1 &&
    echo OK
    OK
    $ sudo make install_setuids
    $ cd
    $ vi etc/ldmadmin-pl.conf
    ...
    $ ldmadmin stop && rm runtime && ln -s ldm-6.4.5 runtime && ldmadmin start
    ...
    $ less logs/ldmd.log

If you want, we can do the upgrade for you.
