Object

column RFC1155-SMIGauge 
The maximum number of concurrent distinct queries used
by the resolver. A query is identified by query name, type and class.
If the number of distinct queries exceeds this limit, the resolver
will try to find a query from the queue which arrives the earliest.
Replace it with the new query if it has been in the queue longer than
the allowed time. The default value is 1024.
