Wheezy
8G ‘Good’
Pi 2
Just noted over the last few days that the RAM indicates slow increase over time. Just housekeeping or something in the code or may not be an issue at all…
Reboots to say 17% and was up to 78% after 18 hours

I’ve noticed the same. I’m also on Wheezy and Pi2 with a 32GB class 10 card.
In addition, I’ve noticed the cpu is also pinned. Here’s the output from top:

I am running a couple other services on the same device, as you can see. It’s running the Z-Way, and I’m serving up a couple of NFS shares. Both of these services were functioning just fine before I installed Cayenne.
I’ll add a +1 to this. I noticed that my RAM usage starts out around 20% on boot up then slowly grows until almost 90% then hovers there.
Have 95% to 98% down here…
Yes reboot refreshes to 8% to 15%
~ Andrew
I thought I would add to this since I have seen it as well. I have attached a screenshot showing that the dashboard memory usage doesn’t even match the task manager usage. As shown this is with an uptime of roughly 16 hours and nothing but the basic widgets running. (Class 10, 32gb card)
Thanks for posting this Dane! Screenshots are always appreciated around here 
We’ll be releasing some fixes soon… @svazir @akaranfilian

Having the same issue. I had set my Pi to restart when memory was at 98% and it kept boot looping even when the memory was at 20%
Same here! Exponentially RAM!!! please fix it!

Do you need logs?
Regards,
Yes, we are definitely going to release an update to make this better. Hang in there! We always want logs 
…feel free to PM them to me?
-B
Please release a new version!
Thank you for this magnific system!
Regards,
Cesar.
When new version?
Please!
Please new version. Every 12 hours raspi hangs because memory exhaust.
Regards,
We have a fix for this. We are doing final rounds of testing and plan to release around 2pm PST today.

Wooo! Thanks!
What we have to do?
Of course! In future we are planning to do more frequent release…the last release we did was a month ago.
You don’t have to do anything…Updates are applied automatically.
-B
It is…we are still making sure everything is stable though. I’ll post official release notes once we are done testing!
-B
Keep testing… much appreciated!
My memory utilization is holding steady over the last hour or so, which is new and welcomed.
Cheers!
