Hi, I'm planning to upgrade an existing home FS setup to the latest available version. Version used : FreeSWITCH Version 1.8.0+git~20170802T153919Z~417639a1b1~64bit (git 417639a 2017-08-02 15:39:19Z 64bit) local_ip_v4 is setup in vars.xml as it seems autodetection doesn't fully work. When stopping FS by running "shutdown", FS goes through the whole stop sequence but doesn't exit in the end, I have to send -KILL signal to the process to stop it. freeswitch.log doesn't show any immediate reason. ptrace of the FS process while stopping shows what seems to be a loop : 17589 freeswitch RET select 0 17589 freeswitch CALL select(0,0,0,0,0x7fffdfeccf00) 17589 freeswitch RET _umtx_op -1 errno 60 Operation timed out 17589 freeswitch CALL _umtx_op(0x80062e098,UMTX_OP_WAIT_UINT_PRIVATE,0,0x18,0x7fffdfe8fe28) 17589 freeswitch RET select 0 17589 freeswitch CALL select(0,0,0,0,0x7fffdfffdf10) 17589 freeswitch RET _umtx_op -1 errno 60 Operation timed out 17589 freeswitch CALL _umtx_op(0x80062e098,UMTX_OP_WAIT_UINT_PRIVATE,0,0x18,0x7fffdfe8fe28) 17589 freeswitch RET select 0 17589 freeswitch CALL select(0,0,0,0,0x7fffdfeccf00) 17589 freeswitch RET _umtx_op -1 errno 60 Operation timed out 17589 freeswitch CALL _umtx_op(0x80062e098,UMTX_OP_WAIT_UINT_PRIVATE,0,0x18,0x7fffdfe8fe28) Supplemental information : - 1.6.19 shows the same issue. - FS installed and ran as root or unprivileged user shows the same issue. Should I file a JIRA, please ? Thanks Éric Masson
