Good morning,

What exactly is the problem with having data in your queue that is over an hour old? That is actually a good thing as it allows downstream hosts some flexibility (if they are configured to accept data over an hour old).

Recently, we have seen an increase in the number of products in our LDM product

I have increased our queue from 2G to 4G and our slots from default to 60,000.

However, I am still seeing the age of the queue go beyond 1 hour (3600).
