Mark,

I don't know what "acqserver" is.

The product-queue module in the LDM library is designed to allow
concurrent access to the queue by multiple processes.

Can you tell what process is causing the disk "thrashing"?

A second LDM can be installed on the same system.  Another user-name
must be used (e.g., "ldm2").   A different port must be specified 
using the "--enable-port=..." option of the "configure" script.  A downstream
LDM will have to be told to use this different port in their the REQUEST
entries in its LDM configuration-file (e.g., "REQUEST NPORT .* 
some.host.name:port").
