Additional info:

The following qpid tools attempt to retrieve a large number of management objects from the broker as part of their normal operation:

qpid-stat,
qpid-config,
qpid-route,
qpid-cluster,

All of the above tools use the QMF getObjects() method call to retrieve all objects of a given class, "queues" for example.  If a large number of objects are defined, then the getObjects() method may not complete before its default timeout expires (60 seconds).

Possible approaches:

*) allow the user to manually override the default timeout via a command line option.  To override the default timeout, the "_timeout" parameter may be passed to getObjects()

*) Put a count of objects for each class type in the broker object.  The tools could use the count to determine if the default timeout should be overridden automagically.

*) QMF V2 will provide a feature where a list of just the object identifiers are returned, rather than a list of the complete objects.  This may be used by the tool to get a summary of all known objects more efficiently that transferring the whole objects themselves.
