Kibana: Kibana's memory limit won't change. Even to default

[ade.syseng (Ade D.)]

Hi,

I'm just upgraded Kibana to 7.12. And I noticed Kibana's memory limit configured at 4GB according to Stack Monitoring.

So then I set the memory limit to 2GB, it was a success. Sometime later, due to web server limitation, I changed Kibana's listen port to 80 and 443 to access Kibana directly without a web server and enabled these configurations to allow Kibana to listen on lower port number:

setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana
setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-plugin
setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-keystore
setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-encryption-keys
setcap cap_net_bind_service=+epi /usr/share/kibana/node/bin/node

Then I noticed Kibana's memory limit changed to 4GB again ignored my configuration. I have tried to change the memory limit in:

/etc/sysconfig/kibana
/etc/kibana/node.options

Even forcing in:

/usr/share/kibana/bin/kibana
/etc/systemd/system/kibana.service

None of them was working. Kibana memory limit still configured at 4GB.
I also tried to delete the memory limit configuration "--max-old-space-size=2048", but still not working.
According to this guidance, Kibana's default memory limit at 1.4GB.

Any suggestion or solution for this issue?

Regards,
Ade

Hey Ade,

Can you share the permissions set for /etc/kibana/node.options? I'm wondering if the file isn't readable by the kibana user.

Hi @jbudz ,

Thanks for the respond. Here's the permissions:

Any clue? permissions seems correct.

Hi @jbudz,

I think I found a temporary solution to my problem. All I need to do is to add the memory limit configuration "--max-old-space-size=2048" in:

/usr/share/kibana/bin/kibana

in this line, like this:

NODE_OPTIONS="--no-warnings --max-http-header-size=65536 --tls-min-v1.0 $KBN_NODE_OPTS $NODE_OPTIONS" NODE_ENV=production exec "${NODE}" --max-old-space-size=2048 "${DIR}/src/cli/dist" ${@}

and here's the result:

but I think this is not standard to set Kibana's memory limit. Any thought?
