Hello, Tried to upgrade on prompt from 3.2.0.beta3-dev to 3.2.0.beta3 and it broke my Discourse instance due to out of memory during ember build of assets. Tried ./launcher rebuild app with same result. FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory 1: 0xb83f50 …

[image] Andrei Dolanescu: so I can’t afford to resize it with more memory. You would only need to resize it during the rebuild.

Do you have Swap? What is the output of free -h

total used free shared buff/cache available Mem: 952Mi 321Mi 414Mi 3.1Mi 374Mi 631Mi Swap: 2.0Gi 75Mi 1.9Gi

Hello and welcome @andreid :slight_smile: My 1GB DO test site has been struggling with memory issues during rebuilds recently too. I temporarily upgraded to a 2GB just to get it over the line.

It might be worth the effort to now update the minimum requirements in docs to 2GB RAM then?

I remember it happening last year and some tweaks were made JavaScript heap out of memory due to Ember CLI - #4 by JammyDodger . I’m not sure if something can be done this time too, but I’ll ask. :+1:

Thank you @RGJ and @JammyDodger , temporarily resizing it did the trick.

Adding 1G of swap should be functionally the same as adding 1G of RAM, if you have the disk space to do it. (It will probably take longer to run the upgrade, but that’s performance, rather than function. What you desire is to avoid the out of memory situation.)

I have additional info in case it helps mitigate the issue from Discourse’s end. My instance (DigitalOcean ~1GB droplet w/ 2GB swap) recently began taking significantly longer to rebuild and reporting the same fatal error about 3 out of every 4 times (luck seems to improve after running ./launcher c…

[image] Troid92: perhaps 1024 is an artificial ceiling we’re hitting against that Discourse rebuilds can no longer be contained in. That is a very good point! Right now we up it to 1024mb on low-RAM machines here . We could certainly experiment with increasing that to 1500 or 2000 and see if i…

Looks good to me! Obviously 30m+ rebuilds are still not ideal, so I hope we can improve things in the not-too-distant future. But this seems like a good solution to stop the bleeding.
