Service Fails

[Mdleal]

Are you having issues with the application crashing because the wink is out of memory? Maybe I'm just sending too many messages. I have an Aeon Energy plug that updates every few seconds.

Are you running the latest code? I added a check to limit calls to checking the wink database if a check is already running.

I last updated when you fixed the 2.49 db issuse.

child_process.js:958 throw errnoException(process._errno, 'spawn'); ^ Error: spawn ENOMEM at errnoException (child_process.js:1011:11) at ChildProcess.spawn (child_process.js:958:11) at exports.spawn (child_process.js:746:9) at Object.exports.execFile (child_process.js:628:15) at checkDatabase (/opt/local_control/wink-mqtt/wink-mqtt.js:73:22) at Tail.deviceStatus.(anonymous function) (/opt/local_control/wink-mqtt/wink-mqtt.js:29:9) at checkDatabase (/opt/local_control/wink-mqtt/wink-mqtt.js:73:22) at Tail.deviceStatus.(anonymous function) (/opt/local_control/wink-mqtt/wink-mqtt.js:29:9) at Tail.emit (events.js:95:17) at /opt/local_control/wink-mqtt/node_modules/always-tail/index.js:78:32 at Object.wrapper as oncomplete

Just updated my wink-mqtt.js and same issue. Maybe it is my startup script.

!/bin/sh

case "${1}" in start) echo -n "Starting mqtt..." /usr/bin/node /opt/local_control/wink-mqtt/wink-mqtt.js >> /var/log/mqtt.log 2>&1 ;; stop) echo -n "Stopping mqtt..." killall wink-mqtt.js ;; restart) ${0} stop sleep 1 ${0} start ;; *) echo "Usage: $0 [start|stop|restart]" ;; esac

[Mdleal]

I added the following to the startup script. Let's see if that helps. --max_old_space_size=5 --max-stack-size=5 --max_executable_size=5

[danielolson13]

Let me know if that works. That's how the native local-control node server is started and how I am running my wink-mqtt.js. I do not have a device that sends updates every few seconds, so that may be the difference.

Switched things up with the startup process. Used this tutorial and have monit monitoring the service. https://gun.io/blog/tutorial-deploy-node-js-server-with-example/

What is your free memory at (free -m)?

               total         used         free        shared        buffers

Mem: 59 55 3 0 0 -/+ buffers: 55 3 Swap: 0 0 0

Are you still having issues? I had issues with spawn running out of memory in the past, but not with the current version. I do not have a zwave device that updates it's status, so that may be the difference. Hitting the checkDatabase function while it was still waiting for the last check to complete causes that error.

[Mdleal]

No issuses since i adjusted my startup script.

[danielolson13]

Can you share what you added to the /etc/monitrc for monitoring the process?

[Mdleal]

Check out https://www.reddit.com/r/winkhub/comments/474gg7/so_now_that_we_have_local_control_will_we_get_an/

We have been discussing your project. Guy said we can disable AAU and Heartbeat to get more memory. I would also like to disable lutron. Here is my start scrip and monit

/etc/rc.d/init.d/mqtt

!/bin/sh

case "${1}" in start) echo -n "Starting mqtt..."

while ! ping -c 1 -W 1 192.168.1.1; do

  #   echo "Waiting for 192.168.1.1 - network interface might be down..."
  #   sleep 1
  #done
  #sleep 10
  node --max_old_space_size=4  --max_executable_size=4  /opt/local_control/wink-mqtt/wink-mqtt.js 1>>"/var/log/mqtt.log" 2>&1 &
       echo $! > "/var/run/mqtt.pid";
  ;;

stop) echo -n "Stopping mqtt..." killall wink-mqtt.js kill cat /var/run/mqtt.pid ;;

restart) ${0} stop sleep 1 ${0} start ;;

*) echo "Usage: $0 [start|stop|restart]" ;;

esac

/etc/monitrc - at the bottom of the file

check process nodejs with pidfile "/var/run/mqtt.pid" start program = "/etc/rc.d/init.d/mqtt start" stop program = "/etc/rc.d/init.d/mqtt stop"

I have 15 free memory with disabling AAU and Heartbeat in /opt/local_control/servers.js

[danielolson13]

Hmmm, I don't have any more memory freed by removing aau and heartbeat from start in /opt/local-control/server.js and now it take about 3 minutes for my wink to reboot. I'm not having any memory issues, I've been running for 24 hours with the same PID.

[Mdleal]

Changes to server.js. do you still see them running?

heartbeat_port : 8886

, aau_port : 8888

And , start : 'wifi'
