Critical Alarm: Memory Exhausted

[tac84]

Really strange one here.
All of a sudden I'm getting Critical Alarms: Memory Exhausted for the SD Card. 8GB card I believe.

Details of system:
R11.1.3.1.0 build 34 (I've been on this release for a while)
Essential Edition

This has only just started happening following no change to settings/environment.

Formatted the SD Card using Manager and rebuilt the SD Card (A-Law). This results in usage of about 30% of the card.

A week or so later, the SD card is full.

Any ideas?

I would put the card into a card reader and check what directories consume the most space to see what fills up the card.

I like to use the Tool Treesize for that.

Great advice, thank you. This was the result. I'm going to rebuild the card and monitor it.

Strangely, the system just rebooted itself and now the memory card usage is back down to 30%....

Some systems (usually linux) with a Journaling file system keep disk space locked even after deleting files. Maybe this was similar and the reboot freed the space. But this is just a guess.

Thanks again for the advice, derfloh. Always greatly appreciated.

Hi all

This one has become an issue again.

I've been monitoring the 'Resources' tab in System Status. I find that over the course of several days, the memory card will see large increases to space used. After 4-5 days, the card shows as full and Alarms naturally begin to report. If I reboot the system, the memory card drops back down to the usual usage of around 30% and then slowly over 4-5 days the card becomes full again.

Nothing really has changed on the system. I've been on R11.1.3.1.0 build 34 ever since it came out and this only started happening in the last month. Not a huge problem given I can resolve it with a quick system reboot, just curious as to what could be causing this and if anyone has noticed similar behavior.

Also, this system is just in use in a home office environment so no heavy use.
