@yk also consider increasing the system swap space

yk

@sdetweil that’s a good point. It happened again - I gather that’s probably a best option.

Keep me honest, is the below the best approach?

For others searching in the future:

sudo dphys-swapfile swapoff
sudo nano /etc/dphys-swapfile
update CONF_SWAPSIZE to something like 1024
save file (ctrl + x)
sudo dphys-swapfile setup
sudo dphys-swapfile swapon
sudo reboot

You’re probably right, need to increase. Mine is set to 100 at the moment.

@yk yes, good steps

free -m

will tell you if any has been used

@sdetweil keeps happening unfortunately. it might be time to start removing modules to see if that helps.

Two errors seen:
out of memory error and also saw a fatal: unable to access ‘https://github.com/MichMich/MagicMirror.git/’: gnutls_handshake() failed: Error in the push function.

I’m only using:
MMM-MyWastePickup (only uses local file)
MMM-Unsplash (hits Unsplash twice an hour)
MMM-DarkSkyForecast
MMM-Tools
Calendar does an iCloud refresh using vdirsyncer (every 30 minutes)

Calendar-Fetcher looks to be doing a broadcasting of events every 10 to 12 minutes. Not sure what this is.

mem total=925 / used=272
swap total=1023 / used=116

I wonder if the iCloud hit happens at the same time as the Unsplash hit causing an issue.

@yk said in Development Branch -- Screen Going Blank:

Not sure what this is.
mem total=925 / used=272
swap total=1023 / used=116

if swap was 100, now 116 meg used.
memory 272 used doesn’t make sense

yk

@sdetweil sorry

I bumped up the swap already to 1024

memory
total = 925
used = 272

swap
total=1023
used=116

sdetweil

@yk shouldn’t have used any swap if u still have free main memory

yk

@sdetweil agreed.

But i’m seeing the below after another memory issue today.

type total used free shared buff/cache availabl
Mem: 925 291 367 9 267 571
Swap: 1023 93 930

@sdetweil I’m working with the developer of MMM-Unsplash. This might be down the the usage of “raw”. Will revert.

Separately, just to confirm: no issue with calendar fetcher broadcasting every 10 minutes? What is it doing? (can you tell I’m sniffing everything now?) ;)

yk

@sdetweil let’s close this one. There was a need to pass through a height or width value when using MMM-Unsplash. Passing nothing seems to have grabbed the raw file and chewed up a good deal of memory. I’m still monitoring.

I’d love to setup a log element that drops memory usage into the pm2 logs. Just fear monitoring memory may eat up too much memory ;) (but I should have plenty of it)

I’m using MMM-Tools to display stats, may leverage that.
