Sounds like your queue is plenty big enough.

There have been two improvements to the downstream LDM code and one
improvement to the upstream LDM code since the version of the LDM
that you're running.  These improvements all dealt with ensuring that
no products would be missed.  I therefore suggest that you install the
latest version of the LDM at your site and try to get your customers
to install it at theirs.

Please let me know if this does or does not solve the problem.

Regards,
Steve Emmerson
