[LDM #RSJ-676480]: pqinsert and pqcheck segfaults



John,

[I copied your "ldm-users" email into our support-email system.]

The error you saw was due to the failure of a sanity-check of the product-queue
when it's opened. This should not have occurred.

Was any other process simultaneously accessing the product-queue? Was the LDM
running or was it stopped? Was a crontab(1) entry accessing the queue?

Did something happen that could have corrupted the queue? Did the computer
crash? Did the power go out?

In order for the LDM system to continue, the product-queue will have to be
re-created.
