Help: FATAL Port 5601 is already in use. Another instance of Kibana may be running!

Elastic Stack Kibana

I have update my versions of elasticsearch and kibana, and installed with no problems using brew on my mac. However, when I try to execute 'bin/kibana' I get the following:

Johns-MacBook-Pro:kibana-5.2.2-darwin-x86_64 johnhrburns$ bin/kibana
log [08:32:31.111] [info][status][plugin:kibana@5.2.2] Status changed from uninitialized to green - Ready

log [08:32:31.313] [fatal] Port 5601 is already in use. Another instance of Kibana may be running!
FATAL Port 5601 is already in use. Another instance of Kibana may be running!

When I try to find the PID and kill any other instance of Kibana I can't find anything:

Johns-MacBook-Pro:kibana-5.2.2-darwin-x86_64 johnhrburns$ ps -ef | grep kibana
  501  9850  4747   0  9:38AM ttys000    0:00.00 grep kibana

Please help! Thanks!

@johnhrburns you can use the following command to see the PID that is listening on port 5601

lsof -i :5601

You could also use a derivate of your original approach looking for the process named 'node'

ps -ef | grep node

but this has the potential to return processes besides the one you're looking for
