Hi, My poudriere builds rust on a Raspberry PI with 8 GB RAM which is doing all kinds of other stuff like running Jenkins in the meantime. So I doubt your RAM is the issue.
I once helped somebody with out-of-memory problems and that person had set MAX_MEMORY in poudriere.conf to a really low value for testing purposes and than forgot about it. What would help is if you post a link to the full build log as at the start of the log it prints all kinds of information about your memory settings. Regards, Ronald.

Hey there folks, I've got poudriere running on a recently-16-ified VM with 8 cores and 48G ram (up from 32), and to eat the dogfood I'm attempting to build all my own packages. lang/rust is a big one. It pontificates for about two hours, then dies with: [ 45% 1690/3710] Building RISCVGenExegesis.inc... [ 45% 1691/3710] Building RISCVGenGlobalISel.inc...

Note that I'm not doing anything multi-threaded with Poudriere, this is single CPU bound. -Dan
