22.05 snaps paused?

Any idea what was using it at the time?
It's not unusual to see memory use like that following an upgrade, especially if you have a bunch of packages that all reinstall.

@bob-dig I had the same issue after upgrading on an 5100. Stupid me forgot to look at where the memory was being used. I just rebooted the router once more and memory usage was right back to where it was before. There were no packages that were reinstalling or anything else updating that I could discern. Sorry for being a bad troubleshooter guys.
-
@stephenw10 Today, after updating from beta to RC, I noticed it again. RAM usage was doubled after the upgrade. No problem for me though 36% RAM usage instead of 17% RAM usage, what I got after rebooting manually.
-
So it doubled after running the upgrade and went back to the previous use after rebooting a second time?
-
@stephenw10 I’m seeing the same thing on my 5100. Memory use is sitting at 43% when it’s normally in the upper teens or maybe 20s. Is there a command I can run that would be more helpful for you all as far as profiling this? This makes two updates, beta and RC where I see this type of memory use post upgrade. I’m confident a reboot would cause the memory use to go back to normal. I’m not worried but don’t want to destroy data that might help you all.
-
Look at the output of
top -HaSP, sort by 'res' to see what's using it.If it's not shown there then it's kernel memory and probably just a remainder from the update process. I would expect it to be freed after some time.

@stephenw10 hope this is of help

Not really, that all looks normal. So I'd have to say it's probably kernel memory.

Good to know. I’ll just restart it at the next opportunity I have when I won’t have to endure the sound of voices suddenly crying out in terror as the Netflix is suddenly silenced.

@stephenw10 said in 22.05 snaps paused?:
So it doubled after running the upgrade and went back to the previous use after rebooting a second time?
Yes. I am just mentioning it again because there might be installations where this is troublesome? But from now on I will be silent about the RAM usage just after upgrading. In the end, RAM is there to be used anyway.
