npm and node_index.js high CPU load

[Joulinar]

so it is running fine now? No CPU spikes anymore?

node-red isn't restarting, but node and npm processes are CPU spiking

than it is not stopping correctly?

using systemctl stop node-red.service is stopping the whole stuff for me and there are no further node or npm processes

[novitibo]

well you could create a script stating node, do a sleep 120 and stop node again. This than to be scheduled on cron

how can I create script for sleep if PID keeps changing?

[Joulinar]

usually it should be

Code: Select all

systemctl start node-red.service
sleep 120
systemctl stop node-red.service

in this whole is the rabbit
node and npm processes are still alive somehow after I stop the node-red

[Joulinar]

how many processes you have? at least in my test system it is a single process that gone as soon as I stop node-red. Are you running something else?

[Joulinar]

strange that it is not gone. As well that you have 2 node processes. Can you use htop and filter (F4) for node

[novitibo]

after node-red is stopped this remains (on and off):

USER root Command node index.js
USER root Command sh -c node index.js
USER root Command node /usr/bin/npm start
