Re: 19990909: pqsurf problems at Lyndon State

Mark,

I looked at your ldm for awhile, didn't find anything major wrong. I did
see some messages about deleting products in the pqsurf queue. I would
increase the size of the pqsurf queue from 3 to 4 megabytes.  Sometimes
the queues get in an abnormal state when the deletion message occur. Keep
me informed.

Robb...
