So this has been observed as gnu make not reaping defunct make/sh processes on openSUSE Tumbleweed. Presumably all the tokens in the shared jobserver read/write fds pipe become tied up by said defunct process, and then make behaves as -j1 at that point. It doesn't happen every time, so it's very time consuming to debug. Eventually the defunct processes are reaped and the build completes mostly in a linear fashion. Am investigating if Ubuntu or Fedora demonstrate the same behavior.
Is there some new glibc or kernel code or compile options that could trigger this sort of (mis-)behavior? Note that Tumbleweed is on gcc8. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
