The pqmon utility doesn't report the size of the product-queue.
Instead, the "maxext" column reports the largest region of contiguous
space in the data portion of the product-queue.

Use the ls(1) utility to obtain the size of the product-queue, e.g.,

    $ ls -l ~ldm/data/ldm.pq
    -rw-rw-r--   1 ldm      ustaff   411369472 Mar 22 16:47 
/local/ldm/data/ldm.pq

> Can I change the queue size?

The size of the product-queue can be changed.  One consequence, however,
is that all of the data it contains will be lost.  Let's first discover
if the size of the  prodduct-queue is the problem.

What version of the LDM are you running?
