<font face="trebuchet ms,sans-serif">This is not supported out of the box, you'd have to write something at a higher level to do that. There may be workarounds if you explain a bit more about your architecture. For example the declare-ok reply when you declare a queue carries the number of messages in the queue, or you may be able to leverage the prefetch-count option to limit the number of messages delivered to a consumer before it acks them, or else use the channel flow control, but the feasibility of each depends a lot on how you have set up your system.<br>

Thanks Emile and Simone for your replies.<br>
<br>
But I want to limit the number of items in the queue and not their<br>
live in the queue.<br>
<br>
Basically my requirement is, I have a queue (called sms_gateway) and I<br>
have several companies publishing messages to that queue. But want to<br>
allocate some big number of size to higher priority companies. Like:<br>
<br>
ABC Company can have maximum of 1000 messages in the sms_gateway<br>
XYZ Company can have maximum of 200 �messages in the sms_gateway<br>
PQR Company can have maximum of 100 �messages in the sms_gateway<br>
<br>
Thanks.<br>
