The system recovered from an unexpected error - RAM overflow

[marbe 20]

I have two HC3s that periodically reboot after an unexpected error, and the most probable error is a RAM overflow. The RAM utilization is high, reaching up to 99%.
Support is unresponsive after 14 days and HC3 is therefore often unavailable.
Has anyone had a similar problem after the last FW upgrade?

My HC3 restarts when memory used > 58

It restarts ever 5-10 days

This was started with a previous update

Thank you for information, but this HC3 is on 99% after a short while after start-up, it is therefore unusable

What do you run on that HC3?

[marbe 20]

Z-WAVE devices, encrypted QAs. It worked well till some last updates.

Revert back to previous FW? What was your normal memory usage?

Perhaps a faulty QA?

Could you be a bit more specific? How many devices? 
 

Have you tried to disable the quickapps (of possible within the quickapp) and turned them on, one-by-one?

It's about 20 encrypted QA and 40 Z-Wave devices.
It is possible that there is a bug somewhere in the QA. Unfortunately, it's hard to find.
Can we take a more detailed look at memory usage? E.g. also the resource usage of each QA?
In general, there is probably a lack of recommendations for developers, there is little to see into the system and it is difficult to detect the problem only by experiments.

That ain't so much in number. 

 

Encrypted quickapps is more hard to see how they work. You could try to disable them, but it depends on how they are build if they actually shut down. But you could give it a try. 

 

If they shut down, you can see how the system acts and start the quickapps one-by-one to see which one gives the trouble. 

 

If they keep on running, the only way is to delete them and install them one by one.
