The maximum number of error reports to queue on a system must be configured to 50 or greater.
The error reporting queue is stored locally on the system and contains the error reports until they have been manually removed or automatically sent to the local collector or DOD-wide collector (if defined). Once a report has been sent to a collector, it is moved to the report archive. Old reports are deleted as new ones arrive once the maximum limit has been met.
