High Memory Usage, is this normal?

@skywatch Can you check with top which uses more CPU?

skywatch

Java is by far the winner in using the most cpu and the most memory... hope that helps...

same here.. see the top output below

in my case I use an orangepi running armbian, the receiver also directly attached to the GPIO header. SInce i use mysgw as a deamon, the CPU usage is higher (therefor runs hotter), compared to an arduino with the sensor attached...

But you are right java seems a bit memory hungry...

Let me know if you need more info

jkandasa

@skywatch Still are you facing this issue after followed this http://forum.mycontroller.org/topic/175/web-page-script-stopped-responding/6 ?

jkandasa

@Tag This is my RPI CPU usage, I use RPI minimal install and WiFI MySnesors gateway(two gateways)

skywatch

I have had to reboot the pi today a few times but am now monitoring memory usage. So far it is rising steadily, but slowly. I will give it a few days and see how it goes.

@jkandasa

I unfortunately cannot get the graph you show.....
did you get it from a script or from the myagent software?

How do I add an image to a post here?

Also, what memory is mcagent reporting? Ram? Sdcard? I have an image screenshot that you might like to see!

jkandasa

@Tag Yes, I use MCAgent to report RPI internals.

@skywatch It is CPU of the RPI.

How do I add an image to a post here?

Just save the image on your local computer and do upload with upload icon when composing message on this forum.

skywatch

@jkandasa

@skywatch It is CPU of the RPI.

That doesn't make sense, memory is separate to CPU surely?

I can only upload images less then 512kb. At that level all detail is lost, can I send directly to your email?

jkandasa

@skywatch Yes, I put 512KB limit to avoid storage full. Yes please send to jkandasa at gmail dot com
