Note that if you are using the AIO based persistent store  for linux 
then you will also unfortunately use up a minimum of 4 filehandles  per 
durable queue.

The excessively large numbers of timer warnings has been fixed on trunk and in 
0.8 release. They are due to heavy use of timers in some parts of the code base 
and seem to be harmless once the volume of the warnings is turned down.

Re: Stating Qpid on Windows

Posted by Lahiru Gunathilake <gl...@gmail.com>.

Hi Adam,

Build qpid/python and set PYTHONPATH to qpid/python directory and go to
command and run qpid-stat --help and see the options.

By using python script in that directory you will be able to create queues,
monitor queues etc.

Thanks
Lahiru

You can use the --data-dir option (see qpidd --help)
