Steve,

Here are the actual LDM queue sizes created by 'ldmadmin mkqueue -f'
on our Fedora Core 2 Linux machine (2.6.6-1.427smp kernel):

$pq_size="4000M"; -> 4273569792

$pq_size="4G";    -> 4376367104

It is interesting that the sizes of the queue are different!

Also, the LDM worked when the queue was 4273569792 bytes, but did not
when the queue was 4376367104 bytes:
