After updating my C7 to the latest release (2.4.1.153) I suddenly get the warning that my hub is running low in memory. Never had this before.
Before a reboot the warning stated 84744
After a reboot the warning came up immediately with 58052.
The value comes from the app "Hub monitor". The threshold for warnings in the app is set to 120000.

I have never had any warnings in the past.

Currently the hub seems not to be very slow.

Any ideas, what to do or where I can see the actual free memory?

Thanks for any help.

Go to this endpoint:
http://YOUR.HUB.IP/hub/advanced/freeOSMemoryHistory

Scroll as far down as it goes, and post a good chunk of the most recent entries. Could be screenshot or text.

Thanks for your response.

Please see the screenshot below. There was nothing to scroll down. The shot shows everything I got.

Currently I don't get any alerts.

Your free memory is fine now, the alerts you got were probably from before the reboot.

Currently at 356,336

Thanks, will have an eye on this over the next few days. Hopefully it stays this way.

What makes me wondering is that all of it started after reboot, initiated by the hub update.

As said before, I will have a look at this.

Thanks for your help!

When the update is downloading the memory can drop a lot, it gets freed up when you reboot. So those alerts may have been from low mem before the update but they did not trigger until after it rebooted.

Once and a while things go sideways right after an update as well, and another reboot is needed.
