https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274284 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #3 from Konstantin Belousov <kib@FreeBSD.org> --- I see python process tightly looping doing nothing but calling sched_yield(), the call comes from libomp.so.1. Most likely cause is the following function: void __kmp_infinite_loop(void) { static int done = FALSE; while (!done) { KMP_YIELD(TRUE); } } I do not know anything about OpenMP runtime to understand more, and binaries do not have symbols. BTW, it seems that Julia build also hangs with the similar syndrome. -- You are receiving this mail because: You are the assignee for the bug.help
