FS freeze with 100% CPU rate frequently
by Eric Ni 14 Dec '15

14 Dec '15

Hi, My FS freeze with 100% CPU rate frequently. When it happens, there is no strange network traffic and no log at all. The last thing logged is just the processing of a normal phone call. Then everything stopped. How can I debug or find any clue about this issue? Thanks.

building v8 treats warnings as errors and will not compile
by Lee Azzarello 14 Dec '15

14 Dec '15

Hello everyone, I'm compiling Freeswitch (both 1.6 and git HEAD as of this email timestamp) and I require a JavaScript interpreter. When the build process hits mod_v8 I get the following error[1]. System info: OS X 10.11.1 (El Capitan), homebrew updated as of this morning, current stable Xcode, all default ./configure options. One thing I noticed is the build system ignores my environment if I export CFLAGS="-Wno-errors" and CXXFLAGS="-Wno-errors". Warnings are always handled as errors because -Werror is always appended to the compiler flags. Thanks, Lee [1] making all mod_v8 cd /Users/lazzarello/src/freeswitch/libs/v8-3.24.14 && (test -f .stamp-patch || patch -t -p0 < /Users/lazzarello/src/freeswitch/src/mod/languages/mod_v8/v8-build.patch) patching file Makefile touch /Users/lazzarello/src/freeswitch/libs/v8-3.24.14/.stamp-patch mkdir -p /Users/lazzarello/src/freeswitch/libs/v8-3.24.14 if test "x86_64" = "x86_64"; then \ defines="v8_target_arch=x64 target_arch=x64"; \ else \ if test "x86_64" = "arm"; then \ defines="v8_target_arch=arm target_arch=arm"; \ else \ if test "x36_64" = "i386"; then \ defines="v8_target_arch=ia32 target_arch=ia32"; \ fi; \ fi; \ fi; \ cd /Users/lazzarello/src/freeswitch/libs/v8-3.24.14 && CFLAGS="" CXXFLAGS="" \ LINK=g++ CXX=g++ GYPFLAGS="" GYP_DEFINES="$defines" \ OUTDIR=/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/out \ PYTHONPATH="/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/build/gyp/pylib:" /Applications/Xcode.app/Contents/Developer/usr/bin/make -C /Users/lazzarello/src/freeswitch/libs/v8-3.24.14 snapshot=off i18nsupport=off library=shared native PYTHONPATH="/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/tools/generate_shim_headers:/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/build/gyp/pylib:" \ GYP_GENERATORS=make \ build/gyp/gyp --generator-output="/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/out" build/all.gyp \ -Ibuild/standalone.gypi --depth=. -S.native -Dcomponent=shared_library -Dv8_enable_backtrace=1 -Dv8_use_snapshot='false' -Dv8_enable_i18n_support=0 -Darm_fpu=default -Darm_float_abi=default CXX(target) /Users/lazzarello/src/freeswitch/libs/v8-3.24.14/out/native/obj.target/v8_base.x64/src/accessors.o In file included from ../src/accessors.cc:28: In file included from ../src/v8.h:62: In file included from ../src/objects-inl.h:38: In file included from ../src/elements.h:33: In file included from ../src/heap.h:36: In file included from ../src/incremental-marking.h:33: In file included from ../src/mark-compact.h:32: ../src/spaces.h:925:26: error: 'this' pointer cannot be null in well-defined C++ code; comparison may be assumed to always evaluate to true [-Werror,-Wtautological-undefined-compare] bool exists() { return this != NULL && code_range_ != NULL; } ^~~~ ~~~~ ../src/spaces.h:927:9: error: 'this' pointer cannot be null in well-defined C++ code; comparison may be assumed to always evaluate to false [-Werror,-Wtautological-undefined-compare] if (this == NULL || code_range_ == NULL) return NULL; ^~~~ ~~~~ ../src/spaces.h:931:9: error: 'this' pointer cannot be null in well-defined C++ code; comparison may be assumed to always evaluate to false [-Werror,-Wtautological-undefined-compare] if (this == NULL || code_range_ == NULL) return false; ^~~~ ~~~~ 3 errors generated. make[5]: *** [/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/out/native/obj.target/v8_base.x64/src/accessors.o] Error 1 make[4]: *** [native] Error 2 make[3]: *** [/Users/lazzarello/src/freeswitch/libs/v8-3.24.14/out/native/libv8.dylib] Error 2 make[2]: *** [mod_v8-all] Error 1 make[1]: *** [mod_v8] Error 2 make: *** [mod_v8] Error 2

Generate RFC2833 DTMF from playback of a wav file with embedded (inband) tones?
by D D 13 Dec '15

13 Dec '15

Hi, We have an application that needs to play wav files. The wav files haveinband DTMF tones. Can I configure FS to detect these tones and instead send out RFC2833 packets? I really hope there is a way, because we have an older DIalogic systemthat does this function, and I really don't want to use that! Thanks,David

High syscall percentage on Centos 7
by Denys D 11 Dec '15

11 Dec '15

Hi! Has anybody faced with high system calls on Centos 7 while running FreeSwitch? We have migrated from FS 1.2.23 on Centos 5.11 to FS 1.6.2 on Centos 7 and faced with very high syscall (up to 60% CPU time) rate under moderate load (300 CPS, 1500 simultaneous calls). We also faced the same issue on Centos 6.7 and Debian 8.2 with FS 1.6.2 on the same hardware. On Centos 5.11 with the same load and h/w we had no more than 10% syscalls CPU time. We have already tried nohz=off kernel option and it didn't solve the problem. What should we change in our environment to achieve the same performance level as it was on Centos 5.11?

mod_rtmp rtmps and get conference video for audio client
by Alessandro Illiano 11 Dec '15

11 Dec '15

Hi all, i’m trying to configure a rtmp endpoint. First question: it’s possible to use rtmps? Second question: i would like to develop a client that can “join” a conference using mod_conference, but if i set an audio only rtmp endpoint, this not receive video layer from conference. When i configure the client using "wantVideo: true” this client can receive the video but also send a blank video to the conference. Thanks Alessandro

Re- UUID logging to freeswitch log file missing for Lua freeswitch.consoleLog() logging
by Andrew Keil 11 Dec '15

11 Dec '15

To FreeSWITCH users, Re- FreeSWITCH version 1.6.5 I just noticed that inside the /log/freeswitch.log file (and also down the Event Socket Layer side) that the uuid is not logged when calls to freeswitch.consoleLog(...) are made from inside a Lua script. For example: freeswitch.consoleLog("INFO", "Test message\n") logs inside /log/freeswitch.log: 2015-12-11 12:27:57.960004 [INFO] switch_cpp.cpp:1356 Test message whereas other logging automatically prefixes with the session uuid (for example): f014f888-44e5-4edc-98e9-420ab2fe3698 2015-12-11 12:14:06.326636 [NOTICE] switch_cpp.cpp:683 Channel [sofia/internal/1000(a)192.168.15.50] has been answered Also when looking into the ESL side I noticed that the same is true for ESL events (Content-Type:log/data) where the "User-Data" header is empty for the freeswitch.consoleLog logging calls, however contains the session uuid for other log messages. My question is whether there is a simple switch inside a configuration file to enable uuid logging from Lua scripts (especially for the freeswitch.consoleLog(...) function calls)? I understand that I could simply add the uuid inside the log message string myself for all freeswitch.consoleLog(...) function calls, however I would have thought that internally (since the uuid is available to the Lua script via session:getVariable("uuid")) that the uuid could be logged like it is in other parts of FreeSWITCH already. Regards, Andrew Keil

High load with low cpu utilization
by Adam Kuśmirek 10 Dec '15

10 Dec '15

Hello We see a high load on server with two 10 core HT processors. cat /proc/cpuinfo shows 40 processors. 1 minute load average is often grater than 70 when processing ~120 concurrent calls. CPU utilization shows 97%idle and 0.1%wa I checked also io stats and everything looks OK. Operating system Centos 7 uname -a Linux pbx-fs-drc.ib 3.10.0-229.7.2.el7.x86_64 #1 SMP Tue Jun 23 22:06:11 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Below link to pastebin with gdb output gdb /usr/local/freeswitch/bin/freeswitch /usr/local/freeswitch/log/freeswitch.gcore.2699 set pagination off thread apply all bt https://pastebin.freeswitch.org/24487 We are planning to run much more concurrent calls but do not understand these stats. Why processes are waiting in queue and we do not see any bottleneck ? Please help

How can I cancel an entire file_string list of files from a playback?
by D D 10 Dec '15

10 Dec '15

Hi, I am playing a list of files using playback with a file_string list. If I send a break command to the channel, then only the currently playing fileis stopped, and then the playback continues on to the next file. I tried to use "break all" but that cancels the entire dialplan application queue,and the call gets terminated. How can I just cancel all the files in the playback file_string? Thanks,David
