[LDM #HCO-891524]: Unidata Performance Question


I'm convinced that your product-queue was corrupted somehow.

Please keep me apprised.

> Steve, The same thing happened again yesterday morning but this time I have 
> log captures to demonstrate what happened.  Pqinsert fails when the max 
> number of slots is reached.  I estimated a file rate for the queue and set a 
> value along with a size in the registry.xml file.  I figured it might make

> larger than what I expected for the number of products it would take to fill 
> the queue.
> In yesterdays case we were receive a larger ingest of smaller files so the 
> product queue had grown to about 16GB but the count of 65536 slot was reached 
> and the log file Iâm attaching shows that pqinsert failed, then the process 
> hung up backed up all the other pqinserts and corrupted the queue.  This was 
> the behavior I was expected.  I was under the presumption that if the max 
> queue slots was reached the oldest product was deleted to make room for the 
> next one.
> To mitigate the problem in the mean time I quadrupled the number of slots in 
> the registry.xml configuration, rebuilt the queue and will watch and see in 
> about 4 more days when the queue fills up how LDM does.

> This is line 67486 of the attached log file:
> pqinsert ERROR: fb layer ran out of product slots, too many products in queue
> Just an FYI for you.
