Connections limit to 28k CCUs

[alinanasir01]

I'm trying to connect 30k mqtt CCUs but the connections limit to 28228.
its with vernemq. The system limits are all set to higher values and my JMeter scripts can work across 1 million but the vmq tests limit to 28225 CCUs.

Is this the correct way to update the listener.max_connections limits?

make_install(git = "https://github.com/erlio/vmq_mzbench.git",branch = "master") pre_hook(): exec(all, "sudo chmod a+rwx /etc/vernemq/vernemq.conf") exec(all, "sudo sed -i '/listener.max_connections = 400000/c\\listener.max_connections = 450000'/etc/vernemq/vernemq.conf") exec(all, "sudo service vernemq restart")
