(was on semaphore operations) Same thing happens with fakeroot-tcp. So it looks like it is not the semaphore ops but the wakeup logic. In one case processes wer waiting in sk_wait?? or so and one sees libfakeroot: read: Connection timed out after awhile. Wereupon the build continues for a while until it hangs for good. Another run resulted in hangs during futex wait: $ strace -p8015 Process 8015 attached - interrupt to quit futex(0x2b6bd51d0640, FUTEX_WAIT_PRIVATE, 2, NULL There are always some zombies around when this occurs. 0 1000 8015 7712 20 0 18632 6796 futex_ S+ pts/0 0:00 /usr/bin/make -f scripts/Makefile.build obj=drivers/net 0 1000 8239 8015 20 0 0 0 exit Z+ pts/0 0:00 [make] <defunct> 0 1000 8240 8015 20 0 0 0 exit Z+ pts/0 0:00 [make] <defunct> 0 1000 8251 8015 20 0 0 0 exit Z+ pts/0 0:00 [make] <defunct> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
