https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225863 Bug ID: 225863 Summary: Regression between 10 & 11, Freeswitch hangs when exiting Product: Base System Version: 11.1-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: threads Assignee: freebsd-threads@FreeBSD.org Reporter: emss@free.fr Created attachment 190575 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D190575&action= =3Dedit backtrace Freeswitch, a multiprotocol softswitch (http://freewitch.org) runs on FreeBSD and a port is available (net/freeswitch/) Freeswitch runs fine on any 10.x installation, issueing the shutdown command from cli makes the application exit cleanly. On any 11.x installation, issueing the shutdown command from cli makes the application hang. FreeBSD version is : FreeBSD newsrv.interne.associated-bears.org 11.1-STABLE FreeBSD 11.1-STABLE= #0 r327876M: Sat Jan 13 16:19:26 CET 2018=20=20=20=20 emss@newsrv.interne.associated-bears.org:/usr/obj/usr/src/sys/SE7525GP2 am= d64 Generic or custom kernel behave the same. On Freeswitch side, 1.6.19 (net/freeswitch) and also git branches master & v1.6 show the same issue. I've reproduced the issue on the latest v1.6, the backtrace of stuck process shows the following : #0 0x00000008030ea91c in _umtx_op_err () from /lib/libthr.so.3 #1 0x00000008030e6f97 in join_common (pthread=3D0x807ed7700, thread_return=3D0x7fffffffb658, abstime=3D0x0) at /usr/src/lib/libthr/thread/thr_join.c:125 #2 0x0000000800f01421 in apr_thread_join (retval=3D0x7fffffffb68c, thd=3D0x8059e9658) at threadproc/unix/thread.c:234 #3 0x0000000800cd889e in do_shutdown (module=3D0x2, shutdown=3D<optimized = out>, unload=3DSWITCH_TRUE, fail_if_busy=3D(unknown: 1523667750), err=3D<optimize= d out>) at src/switch_loadable_module.c:2031 #4 0x0000000800cdb84a in switch_loadable_module_shutdown () at src/switch_loadable_module.c:2083 #5 0x0000000800c9d92c in switch_core_destroy () at src/switch_core.c:2940 #6 0x0000000000403b2b in main (argc=3D<optimized out>, argv=3D0x7fffffffe9= 88) at src/switch.c:1210 It seems the issue lies in thread handling. I've attached : - the output of a Freeswitch related script used to gather relevant information. - source files showing in bt Thank for help. =C3=89ric Masson --=20 You are receiving this mail because: You are the assignee for the bug.=
