[asterisk-users] [SOLVED] Re: Feature Request: what about "core stop panic" ?
I think were getting closer: I did: - I edited /etc/default/asterisk to include : AST_USER="root" AST_GROUP="root" # systemctl daemon-reload # systemctl start asterisk # ps aux | grep asterisk root 3602 7.1 2.5 60332 26012 ? Ssl 16:00 0:03 /usr/sbin/asterisk -U root -G root -g # rasterisk # pkill -SEGV asterisk Then console showed: Segmentation error (core dumped) and a /core file is created I also tried with asterisk run asterisk user and group and looked for any newly created (find / -cmin -2) : nothing looking like a core file, though I might overlooked it. So, it really look like a configuration issue: "how to specify, with asterisk and systemd among others, where core files are dumped ?". I'll read again this thread advices and report back here. 2016-09-07 21:44 GMT+02:00 George Joseph <gjoseph at digium.com>:> > > On Wed, Sep 7, 2016 at 11:15 AM, Olivier <oza.4h07 at gmail.com> wrote: > >> >> >> 2016-09-06 17:48 GMT+02:00 Tzafrir Cohen <tzafrir.cohen at xorcom.com>: >> >>> On Tue, Sep 06, 2016 at 06:37:52AM -0600, George Joseph wrote: >>> > On Tue, Sep 6, 2016 at 1:55 AM, Olivier <oza.4h07 at gmail.com> wrote: >>> >>> > > Where should core file be created when Asterisk is run as a daemon by >>> > > asterisk user and group ? >>> > > Is there a setting I can use to specify the directory used (so that >>> we can >>> > > make sure appropriate ownership is set) ? >>> > > >>> > >>> > "$ sysctl kernel.core_pattern" will show you where core files are >>> written. >>> > For Asterisk to produce the core file, it has to be started with the >>> '-g' >>> > option so make sure your asterisk.service file is adding the option. >>> >> >> My asterisk.service is : >> >> # cat /run/systemd/generator.late/asterisk.service >> # Automatically generated by systemd-sysv-generator >> >> [Unit] >> SourcePath=/etc/init.d/asterisk >> Description=LSB: Asterisk PBX >> Before=runlevel2.target runlevel3.target runlevel4.target >> runlevel5.target shutdown.target >> After=network-online.target systemd-journald-dev-log.socket >> nss-lookup.target local-fs.target remote-fs.target dahdi.service >> misdn.service lcr.service wanrouter.service mysql.service postgresql.service >> Wants=network-online.target >> Conflicts=shutdown.target >> >> [Service] >> Type=forking >> Restart=no >> TimeoutSec=5min >> IgnoreSIGPIPE=no >> KillMode=process >> GuessMainPID=no >> RemainAfterExit=yes >> SysVStartPriority=2 >> ExecStart=/etc/init.d/asterisk start >> ExecStop=/etc/init.d/asterisk stop >> ExecReload=/etc/init.d/asterisk reload >> >> >> My /etc/init.d/asterisk file is sourcing my /etc/default/asterisk which >> includes an (uncommented) line COREDUMP=yes. >> I also have >> # grep core /etc/asterisk/asterisk.conf >> dumpcore = yes >> >> make menuselect shows: >> [*] DONT_OPTIMIZE >> [*] COMPILE_DOUBLE >> [ ] DEBUG_THREADS >> [*] LOADABLE_MODULES >> [ ] DEBUG_FD_LEAKS >> [*] BETTER_BACKTRACES >> [ ] LOTS_OF_SPANS >> [ ] MALLOC_DEBUG >> [ ] DEBUG_CHAOS >> [*] BUILD_NATIVE >> --- Extended --- >> [ ] REF_DEBUG >> [ ] AO2_DEBUG >> [ ] STATIC_BUILD >> XXX REBUILD_PARSERS >> [ ] LOW_MEMORY >> [ ] DISABLE_INLINE >> [*] OPTIONAL_API >> XXX USE_HOARD_ALLOCATOR >> [ ] RADIO_RELAX >> [ ] G711_NEW_ALGORITHM >> < > G711_REDUCED_BRANCHING >> < > TEST_CODING_TABLES >> < > TEST_TANDEM_TRANSCODING >> [ ] ADDRESS_SANITIZER >> [ ] THREAD_SANITIZER >> [ ] LEAK_SANITIZER >> [ ] UNDEFINED_SANITIZER >> [ ] BUSYDETECT_TONEONLY >> [ ] BUSYDETECT_COMPARE_TONE_AND_SILENCE >> [ ] BUSYDETECT_DEBUG >> [ ] INTEGER_CALLERID >> >> >> Is there a way to read Compiler Flags from a running system without >> looking at source file directory ? >> >> If someone forgets to select appropriate Compiler Flags, does it prevent >> Asterisk to produce a core file (even an empty one) ? >> > > If -g is specified a core file should always be produced.
