I think you may benefit from reading some more topics on the subject. If you have a search of the #documentation, or just a search in general, I think you’ll find plenty of information that should help fill in the gaps in your knowledge. There is a substantial amount of advice that covers the basics that you can learn from. :+1:

Because running the website (albeit with fewer Unicorns) + performing a build at the same time is costly in memory? I tried this out on my server (3 VCPU, 4GB): Online: 2.21 before upgrade → 1.7 as it frees up memory → 3.5 peak during build (GBs) Swap also went up ~200MB to peak ~800MB Command line (not apples to apples as just after the above) 1.7 before upgrade → drops to ~250MB! → climbs and climbs to peak 3.25 during assets compilation, but generally much lower. Swap usage was very low during almost the entire process. Caveat: all figures observed in htop so may be inaccurate, probably best to graph it. I was surprised how “peaky” offline rebuilds were. Assets precompile definitely uses a lot of memory - perhaps more the more VCPUs you have as it might do some of that in parallel? I was also suprised how little difference the peak was in my case, though swap usage was significantly lower and generally, memory use was much lower for an offline rebuild, remaining in the 100’s of MB during 95% of the process, whereas an online upgrade was minimum 1.7GB.

[image] Robert: Because running the website (albeit with fewer Unicorns) + performing a build at the same time is costly in memory? That seems correct, no need for a question mark there! So rebuilding the app then automatically updates to most recent version it seems? [Screen Shot 2024-02-01 at 4.39.44 PM] Is there a supported or non-supported way to keep previous versions of discourse running, or do new installs for previous versions?

No, but you can slow things down by changing to stable. Unfortunately you just missed the boat this time as you can’t go backwards.

Ok, may want to change to that stable setting for only stable tested updates not the developer/beta ones. Looking to figure out how to do that.

This suffix doesn’t appear in the UI, so this is a technicality which will have no impact on the vast majority of people. For the technical details, see below: In the beta series for Discourse 3.1 and below, our versioning strategy was to ‘release’ a beta, and then leave the version number in tests-passed exactly the sam…

Have read through those now, haven’t yet figured out how to change update settings for stable vs. main / beta / or tests-passed. Edit: Could be the answer is there isn’t a setting for this, maybe dev updates can only be done manually or something? Am just guessing don’t know.

Side note: During rebuild have notice that: 110:M 11 Feb 2024 04:26:05.828 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect. Not sure how to do this, how is this done does anyone know?: add 'vm.overcommit_memory = 1' to /etc/sysctl.conf

I think this has strayed quite far beyond the original question. Let’s close this off now it’s solved and you can start a new topic on installing a stable version.
