当超过1000位收件人时，Rabbitmq无法发送新闻稿

Question

I have a Rabbitmq server and I wish to send out newletters. The problem is I'm uploading the recipients with a .csv file and if it has more than 1000 lines, the error occurs.

Somehow I suspect the following line to be fault:

MQ.fanout(exchange).publish(Marshal.dump(data))

The messages are not being transported for the queues or I don't know.

What I can do is: I have to delete the actual "stuck" project because I can't send any onther newsletter feed until it is deleted. After I delete it, the rest of the newsletters will be sent out perfectly.

Edit:

the logs did not show any errors. However, after setting the log to a lower standing, I've got this:

/var/log/rabbitmq/error.log

This might be a clue?

Answer 1

{frame_too_large,4319180,131064}

Try to increase frame_max parameter as described here https://www.rabbitmq.com/configure.html

[
  {rabbit, [
     {frame_max, 4319180},
    ]
  } 
].

Answer 2

Ultimately we have found the sollution. It was basically what CHAPa said, the rabbitmq was able to recieve bigger frames than the standard (we've set the frame_max for 0). But couldn't find the AMQP file that passes the info. This is where we have found it:

/opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/amqp-0.7.0/lib/amqp/client.rb

And had to change the frame_max value to 0 manually. From this point, it works like a charm. :) Thank you for the advices.

BTW: If I'm gonna be in charge when we scrap this server, I won't upgrade it, or install another Rabbitmq server. PHPlist is my style :) Vote please this up, so it can be on top when somebody searches it.
