Memory Shortage Avoided - Should I be worried?

So I looked in the forum and the only seemingly related issue seemed to be with start up and impacting an appvm, but i don’t seem to be having those issues… yet? So i wanted to check to see if I should be doing something to ameliorate this issues?

So I got a pop up saying:

“Memory Shortage Avoided

The background service app-qubes\x2dicon\x2dreceiver@autostart.service has been terminated by the Linux kernel because the system is low on memory. Consider closing unused applications or browser tabs.”

thats it, as far as i can remember it was there when i sat down at my computer after leaving it on overnight. I have 64GB of mem which I was thinking was enough so am hoping this can be resolved with a simple setting tweak?

My qubes desktops have either 48gb or 64gb of memory and I’ve never seen that message (not even when memory balancing has been used when opening a new qube which causes a reduction below max memory allocated to other qubes). Your memory should be enough. Is this message for a qube you are starting or for dom0 ?

I am not wholly sure if it was dom0 or an appvm but am assuming it was dom0?

How much memory do you assign to each of your AppVMs?

Hi, the majority get 4GB, about a quarter get 6GB, and one gets 12GB but I never have all of them open at the same time.

Cr*p, happened again. But this time I noticed when i popped up and noted how much mem the opened VMs maxes were. So the error again is:

The background service app-qubes\x2dicon\x2dreceiver@autostart.service has been terminated by the Linux kernel because the system is low on memory. Consider closing unused applications or browser tabs.

So the open AppVMS have max allocations of:

6000, 15000, 4000, 4000, 2000, and 4000

its a hair over 30GB and I have 64GB installed so I can’t figure out what the issuse ist with this. For a bit more context I recently upgraded to 4.3.1 and restored my backups onto this new install but the mem allocations are mostly the same. The one that is given 15GB is what i use for multimedia and the others are just sys- and 1-2 “regular” appvms.

Any thoughts? Please? I keep getting this error, its an annoyance now but as this gets more frequent am a bit worried it might start impacting things?
