Troubles with Kibana

Hello.

I've got a 13.2p9/amd64 server where I have a jail dedicated to 
ElasticSearch+Kibana and I'm having troubles starting and stopping the 
latter.

> # pkg info | grep -E "(elastic|kibana)"
> elasticsearch8-8.11.3          Distributed, RESTful search and analytics engine
> kibana8-8.11.3                 Browser based analytics and search interface to ElasticSearch
> py39-elasticsearch-7.17.9      Official Python low-level client for Elasticsearch
> py39-elasticsearch-dsl-7.3.0   High level Python client for Elasticsearch

> # cat /etc/rc.conf
> #cron_enable="NO"
> kibana_enable="YES"
> kibana_syslog_output_enable="YES"
> elasticsearch_enable="YES"





First problem

When I start the jail (with "ezjail-admin start") Elastic starts, but 
Kibana does not.
syslog shows:
> [2024-02-03T16:14:21.861+01:00][INFO ][root] Kibana is starting
> [2024-02-03T16:14:21.939+01:00][INFO ][root] Kibana is shutting down
> [2024-02-03T16:14:21.939+01:00][FATAL][root] Reason: EACCES: permission denied, open '/var/run/kibana.pid'
> Error: EACCES: permission denied, open '/var/run/kibana.pid'
> 
>  FATAL  Error: EACCES: permission denied, open '/var/run/kibana.pid'

Same happens if I try "service kibana start" afterwards from inside the 
jail.
I can get around this with:
> # touch /var/run/kibana.pid
> # chown www /var/run/kibana.pid
> # service kibana start

However this must be done manually everytime I need to restart the 
server or jail.





Second problem

When I try to stop Kibana, it just hangs indefinitely:
>  # service kibana stop
> Stopping kibana.
> Waiting for PIDS: 28179

syslog reports:

This goes on until I kill -9 the process.

This is particularly problematic in case power goes missing and the UPS 
tries to shutdown the server, which will hang, instead.



Any hint?

  bye & Thanks
