The only way those products weren't sent is if they weren't in the product-queue of the NOAAPort LDM. Given the timing, though, I don't see how that could have happened unless there was a massive influx of new data products into that queue. We do encourage our users to have a product-queue capable of holding at least a hour's worth of data. For us, that means running 70 GB queues. pqmon(1) only gives a snapshot of the queue. This is why we encourage user's to periodically use the "ldmadmin addmetrics" command and plot the results. One can then look at the time-series to determine that the minimum age of the oldest product is still greater than one hour. Alternatively, you can use the command "pqmon -S" and look at the third from the last parameter, MinVirtResTime, to see what the minimum oldest age is. Matter of fact, why don't you send me that output for the NOAAPort LDM. Might prove revealing. > > By "main LDM" do you mean the one I've been calling the "backup LDM"?
