HI All:
For some reason when I create a channel using connection.createChannel it is returning null. When I throw that connection and create a new connection ... from then on it returns a channel for one time ... so i have to discard my connection and create new connection every time I create channel.
I do not know why createChannel returns null.
Any insights?

There is one known issue with createChannel returning null, which has
been fixed in 1.7.0.
This is documented here:
http://hopper.squarespace.com/blog/2009/8/31/hotspot-arithmetic.html
However, this may not be the cause in your case.
Please can you send a cut down version of the code that reproduces the symptom.
Ben

HI Ben:
We are using RabbitMQ 1.6
It is simple code where we use one connection to create channels (almost 100K) but it starts returning null after creating 500 of them.So I discard that connection and create a new connection. But when I create channel from new connection , it creates only one channel and after that it keeps returning null.
I changed my code to call createChannel(int channelNumber) ...it seems to be working ... it has processed like 10 k records. |
