https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270785 --- Comment #1 from Alexander Motin <mav@FreeBSD.org> --- Depending on what the applicaiton/java actually does, I can easily believe that behavior could change after the mentioned commit, but it is not necessary an OS bug, it may be an application bug or a lack of optimization. Previous code always waited for at least 2ms in pthread_cond_timedwait(), no matter what timeout is requested, while after the patch it may wake up much sooner, just in few microseconds. It may be that application really requests wake ups that often, but previously it was not properly honored. For better understanding it would be good to collect information about the actual system calls and their arguments before and after, either with truss or may be dtrace, etc. -- You are receiving this mail because: You are the assignee for the bug.
