Omega 2S, Error 12: Out of memory after installing SD card
-
Hi,
I am keep getting Out of memory error after installing SD card of 16GB.
I followed the steps in http://docs.onion.io/omega2-docs/boot-from-external-storage.html#boot-from-external-storage-mounting-the-external-storage-device for SD card. Still I am facing issue. May I know any one encountered same issue.
Thanks,
Naveen

@naveen_kumar I don't use losant mqtt I use Mosquitto which is designed for use on openwrt, you can just use opkg install mosquitto-ssl
However, to address your space issue, pip creates tmp/cache files and it is possible the tmp file system is getting filled up. You can redirect the temp files when using pip uses the following commands:
cd
mkdir temp
export TMPDIR='~/temp'
pip install losant-mqttpip also has a command line parameter to set the destination for temp files, check the docs.

@crispyoz said in Omega 2S, Error 12: Out of memory after installing SD card:
pip install losant-mqtt
@crispyoz Thanks for the reply. I tried still I am getting creating tempame error. Am I missing anything.
-
@naveen_kumar what are the space requirements for losant mqtt?
-
@crispyoz its 60kb on disk.
-
@naveen_kumar I think the memory error here is referring to RAM and not storage.
With npm there's a
max_old_space_sizeargument that limits the memory usage. I suggest checking if there's a way to do the same thing with pip.

@naveen_kumar I just tested on a stock Omega2+ with no SD card and it is fine, so you're probably just out of memory not storage. Take a look at what processes you have running and how much RAM they are using and kill anything you don't need for a minute.

@Lazar-Demin My bad. Yes it is RAM. How can I add Swap file with SD card, I can see the document is for USB drive. is there any tutorial for it, My understanding was, we add SD card automatically swap file have been added. I see no Swap file has been created.
-
To create swap file, follwo the docs:
https://docs.onion.io/omega2-docs/extending-omega-memory.html
I don't hink you need swap given that I was able to install the losent mqtt without any. Just follow my earlier email, use top command to view your memory use
