I’ve had several two-container bootstraps fail today with errors like ERR_PNPM_RECURSIVE_EXEC_FIRST_FAIL Command was killed with SIGKILL (Forced termination): ember build -prod"] I think once I added swap and had it work the next time. But this has 4GB swap: # free -h total …

I have some kind of memory leak/expansion on one of my servers. At @RGJ ’s sensible suggestion I cron schedule a reboot every 7 days early Monday AM (W. Europe) (We believe we know the plugin with the issue but I’ve not invested the time to work out why there is a memory leak/expansion)

Is the build fetching/using pre-built assets? Or have you disabled that? (or patched core such that the pre-built assets can’t be used)

You have a lot of swap but a great deal is already in use. As a two container setup has less downtime, perhaps it’s true that the current invocation of the server is still running and has clocked up a lot of memory use perhaps due to a leak. Perhaps a restart would help, before the update. Perhaps …

This looks like an OOM kill: I’m on ~2 GiB RAM and in two-container rebuilds the old app + new build overlap pushes memory over the edge. Swap is already ~3 GiB used before bootstrap, so the ember build spike gets SIGKILL’d. Stopping the running container (or doing a one-container rebuild) avoids th…

This looks less like a pnpm or Ember issue, and more like the host simply running out of memory. The key detail is the SIGKILL. That usually means the OS stepped in and killed the process (often via the OOM killer), not that ember build -prod failed on its own. On small hosts, Ember production bui…

It feels like more swap would help. It wouldn’t hurt. Instead of looking at total swap and saying it seems like a lot, look at free swap and make sure you have the headroom for a rebuild.

Also check that you have enabled overcommit. [imagen] Discourse Fails to update in the Admin UI - No matter what I very much believe that once you’ve set overcommit you will need less swap.

[imagen] merefield: I have some kind of memory leak/expansion on one of my servers. At @RGJ ’s sensible suggestion I cron schedule a reboot every 7 days early Monday AM (W. Europe) Sounds like a good idea! Do you reboot the server or just the container? I’ll call this the “solution”, if only …

[imagen] pfaffman: Sounds like a good idea! Do you reboot the server or just the container? The entire server :sweat_smile:

[imagen] merefield: The entire server :sweat_smile: It’s not Windows, for heaven’s sake. :rofl:

Oh boy I remember those days! :grimacing:
