[LDM #EZK-400759]: Problem inserting int ldm prod queue - reg.

Sathya,

The most damming evidence is the output from pqcat(1):

[ldm@cpsbn1-tbdr ~]$ pqcat -l- -s -q /usr/local/ldm/data/ldm.pq
Mar 17 17:09:14 pqcat NOTE: Starting Up (17393)
Mar 17 17:09:14 pqcat ERROR: pqcat queueSanityCheck: Product count doesn't match
Mar 17 17:09:14 pqcat ERROR: products tallied: 249   Value in queue: 1064
Mar 17 17:09:14 pqcat NOTE: Exiting
Mar 17 17:09:14 pqcat NOTE: Number of products 249

The above indicates that the number of products in the queue (1064) is greater 
than the number of products that can be extracted from the queue via the 
pq_sequence(3) function (249). Because this should be impossible, either the 
pq(3) library is misbehaving, or some assumption is incorrect. Due to the large 
difference in the numbers (1064 vs. 249) and the extensive use of the LDM, it 
seems unlikely that the pq(3) library is misbehaving -- so we should check our 
assumptions.

Did the pqcat(1) command above actually produce the above output?

Was anything else accessing the queue at the time of the above pqcat(1) command?
