A few more notes: - Because my workstation uses Ivy Bridge CPU, I do CFLAGS override to be su= re that both my systems and software is compatible with Intel CPUs since 3rd g= en. - My software build script uses ZFS a _lot_ under the hood. Every software PREFIX is a ZFS dataset that is mounted, filled, unmounted, sent every buil= d. Every "software build" is an lz4 compressed ZFS dataset sent to a file. ZFS= got a major upgrade in 13, maybe the issue is related? - I use tmpfs feature a lot. By default, (almost) every build is both ccach= ed and work in RAMdisk (I'm quite sure the zombie processes issue happens when invoked from ramdisk that's temporarily mounted under ZFS dataset mount). I also use LTO caching (if enabled for given software definition). I've been trying to use all system features I can (just because I can and I get nice results from it) - My system build configs are public: https://github.com/VerKnowSys/svdOS/blob/master/etc/src.conf https://github.com/VerKnowSys/svdOS/blob/master/etc/make.conf - I use almost the same scripts (minor changes) for builds since FreeBSD 9.0 (when I started having fun with this stuff) - mostly to get reproducible bu= ilds among OS versions. --=20 You are receiving this mail because: You are the assignee for the bug.=
