Re: [h323plus] OpenMCU shutting down unexpectedly
Here's what I get when I use the debug version of OpenMCU located in : h323plus_src/applications/openmcu/obj_linux_x86_d
You can see that I was able to connect a client and then the second client crashed OpenMCU. The first unit was a polycom vsx-8000 the second was a polycom vs-4000.
I'm guessing the error points to here: 00b61000-00ba8000 rw-p 0077d000 fd:00 450315 /root/h323plus_src/h323plus/lib/libh323_linux_x86__d.so.1.20-beta5
But I'm not sure what to do about it.
Any suggestions are greatly appreciated.

Hi Michael,
I think "make install" always installs the optimized executable. I would enable core dumps ("ulimit -c unlimited") and then execute the debug version of openmcu right out of the compile directory (./obj_linux_x86_64_d/openmcu ....").
When you then crash openmcu, you can start gdb with "gdb ./obj_linux_x86_64_d/openmcu core" and execute a "bt" command to see where it crashed.
Regards, Jan

Jan,
I'm not sure I did this right. I went to the ptlib-2.6.2 directory and executed: make debug make install
That all went fine. Then I moved to the openmcu directory and executed: make debug make install
That all appears to work fine. But when I go to trace it I get:

Hi,
the compile will work if you compile PTLib directly with 'make debug' and don't rely on the OpenMCU makefile to start the compilation of PTLib.

I have OpenMCU compiled/installed from the latest cvs. When I get a third client connected, OpenMCU shuts down unexpectedly. It appears to get a shutdown signal from somewhere. I have attached an strace. Let me know if more info is needed.
Also, in pursuing more info about this, I tried compiling OpenMCU with the debug option and got:

Any other suggestions for making OpenMCU debuggable?

I'm not sure why you don't get de-mangeld symbols in your backtrace and no line numbers, but from what I can see, your OpenMCU crashes, because it is accessing an invalid pointer that is used inside the RTP_JitterBuffer::ReadData() method in a PTRACE statement. This is definitely a bug in the code in either H323Plus or OpenMCU, probably the H323Plus.

Here's what I get when I use the debug version of OpenMCU located in : h323plus_src/applications/openmcu/obj_linux_x86_d
You can see that I was able to connect a client and then the second client crashed OpenMCU. The first unit was a polycom vsx-8000 the second was a polycom vs-4000.
I'm guessing the error points to here: 00b61000-00ba8000 rw-p 0077d000 fd:00 450315 /root/h323plus_src/h323plus/lib/libh323_linux_x86__d.so.1.20-beta5
But I'm not sure what to do about it.
Any suggestions are greatly appreciated.

Hi Michael,
I think "make install" always installs the optimized executable. I would enable core dumps ("ulimit -c unlimited") and then execute the debug version of openmcu right out of the compile directory (./obj_linux_x86_64_d/openmcu ....").
When you then crash openmcu, you can start gdb with "gdb ./obj_linux_x86_64_d/openmcu core" and execute a "bt" command to see where it crashed.
Regards, Jan

Jan,
I'm not sure I did this right. I went to the ptlib-2.6.2 directory and executed: make debug make install
That all went fine. Then I moved to the openmcu directory and executed: make debug make install
That all appears to work fine. But when I go to trace it I get:

I'm not sure what the "(no debugging symbols found)" is referring to...
Any suggestions are greatly appreciated.

Hi,
the compile will work if you compile PTLib directly with 'make debug' and don't rely on the OpenMCU makefile to start the compilation of PTLib.

Hello,
I have OpenMCU compiled/installed from the latest cvs. When I get a third client connected, OpenMCU shuts down unexpectedly. It appears to get a shutdown signal from somewhere. I have attached an strace. Let me know if more info is needed.
Also, in pursuing more info about this, I tried compiling OpenMCU with the debug option and got:

I have set: PTLIBDIR=/root/pwlib PTLIBPLUGINDIR=/usr/local/lib/pwlib/
Any other suggestions for making OpenMCU debuggable?
