I am new to Erlang and RabbitMQ.
I have a node on RabbitMQ on CentOS which I had to reset to restart the message queues. Ever since the restart, the Erlang refuses to start the node. There was an erlang_vm corrupted error that was fixed with a rabbit remove and restart. I've tried net_kerlnel start in erlang shell but it fails.

[root@directadmin ~]# erl

Protocol: "inet_tcp": the name rabbit@directadmin seems to be in use by another Erlang node

I've noticed that someone else had a similar issue and they cited that fixing rule set in iptables resolved their issue. I am not sure how that is done. I've tried service iptables restart but that didn't make any difference

When I try run rabbitmqctl stop_app I get this error

[root@directadmin ~]# rabbitmqctl stop_app
Stopping node rabbit@directadmin ...
Error: erlang_vm_restart_needed

When I try running 'rabbitmqctl stop' I get the vm corrupted error

[root@directadmin ~]# rabbitmqctl stop
Stopping and halting node rabbit@directadmin ...
