[rabbitmq-discuss] publish mandatory/immediate flags

We launched w/ a big partner yesterday (AOL) and we're getting hit  
pretty hard with requests and such and it appears that some requests  
never get made to our export nodes and the responses don't always make  
it back from them at times too.  Seeing that we use rabbitMQ for the  
transport of messages, I have a question regarding the mandatory and  
immediate flags.  One of the basic publish options is as follows:

session.getExchange(), key, basicProps, data);

This has mandatory/immediate set to false.  Could it be that the new  
server load is causing requests to get dropped at times?  What are the  
drawbacks to changing those values to true by using the other call?
