How can I increase erlang process for rabbitmq?

Question

I just changed file descriptor value on rabbitmq , now I want to update erlang processes too. Below is an image that might help to answer my question

Answer 1

According to the official Erlang documentation

the command line argument you are interested in is:

+P Number|legacy

 Sets the maximum number of simultaneously existing processes for this system if a Number is passed as value. 

Valid range for Number is [1024-134217727]

According to the RabbitMQ documentation , there is this environment variable RABBITMQ_SERVER_START_ARGS where you can add that kind of parameters.

EDIT Open a shell prompt and try this:
RABBITMQ_SERVER_START_ARGS="+P 231072" rabbitmq-server

Whenever you find a setting that satisfy you, put this RABBITMQ_SERVER_START_ARGS="+P 231072" in a the file /etc/rabbitmq/rabbitmq-env.conf . If this file does not exist, just create it. Please note that the location for this file changes according to your installation. If you are using RabbitMQ from the tar.gz, probably you will have to create this file in $RABBITMQ_HOME/etc/rabbitmq/

Answer 3

Earlang process increased in a ratio with -ulimit

I'm giving this answer from Ubuntu server perspective.

Enter following command to open rabbitmq config. file

sudo nano /etc/default/rabbitmq-server 

Update/Add and save it using Ctrl+x

-ulimit 126666

Restart your server

rabbitmqctl stop_app && rabbitmqctl start_app
