I would look to minimize your channel usage. There is overhead per-channel on a connection basis. Having run into issues due to unintentionally having too many channels open recently, I'd offer that if you can use one channel on one�connection�instead of two or more channels on one connection, you should.<div>

We're after being able to increase channel_max so that Rabbit can<br>
handle more and not give us errors about not having enough channel<br>
ids.<br>
According to Rabbit documentation on AMQP:<br>
<br>
current status in rabbit: planned<br>
Type: MUST<br>
Actor: server<br>
Reference: connection / tune-ok / channel-max / upper-limit<br>
Text: If the client specifies a channel max that is higher than the<br>
value provided by the server, the server MUST close the connection<br>
without attempting a negotiated close. The server may report the error<br>
in some fashion to assist implementors.<br>
<br>
It would seem the server has to specify this too. But it is not<br>
implemented in Rabbit right now.<br>
<br>
Am I right? Is there no other way of increasing the load handled and<br>
getting rid of the channel ids problem?<br>
<br>
We're using this PHP library which specifies channel_max in<br>
src/main/php/Rabbit/AMQP/Connection.php:69.<br>
The exception we're getting occurs on line 154 of the same file.<br>
