RE: NOAAPORT receive system feeding LDM

Dan,

I was out of the office a couple of days, reason for the delayed answer.
The main problem I see from the log messages is that the LDM queue is not
large enough, causing the Deleting oldest messages.  That is the pqinsert
doing the deleting instead of pqexpire, that's not very efficient at all.
I would double the size of the queue, I believe we are using an 800
megabyte queue on our 4 channel NOAAport machine. Let me know if that
changes any of the corrupt queue problems.

Robb...
