Error trying to send message to rabbitmq

[Esteban Buitrago]

Good morning, 

I´m trying to queue a message to my rabbit but it isn´t queued. I check the error and I get: 

2020-04-24 14:54:47.811 [error] <0.1225.0> Channel error on connection <0.777.0> (10.70.0.106:48290 -> 10.70.0.242:5672, vhost: 'v_host', user: 'user'), channel 6:
operation basic.publish caused a channel exception precondition_failed: message size 449299729 is larger than configured max size 134217728

I had search where I can change that limit but I not found any config file in my server, I just can see /etc/rabbitmq/enabled_plugins and /usr/lib/rabbitmq with subfolders autocomplete, bin and lib.

Rabbit : 3.8.2

Erlang 22.0.7

My rabbit is in a server Ubuntu 18.04.2

Thanks for help.

Hi Esteban,

You should not send messages that large through RabbitMQ. If you have the option to compress the message, you should do that. Otherwise, store the message in a different system and pass a "pointer" (like a URI) to the message through RabbitMQ.

If you absolutely must send a message that large, you can increase the max message size to 512MiB in /etc/rabbitmq/rabbitmq.conf

max_message_size = 536870912

You will have to restart RabbitMQ after creating that file.

Thanks,

Luke
