<p class="MsoNormal">Greetings.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Today my proxy server decided to start crashing with a signal 6 error message. Following the troubleshooting steps on http://www.opensips.org/Documentation/TroubleShooting-OutOfMem, I obtained the memory status output (posted on pastebin
at <a href="http://pastebin.com/0JFyAYXi">http://pastebin.com/0JFyAYXi</a>) on one of the crashes (32Mb private memory 8GB shared memory). Oddly enough, I’m not seeing any out of memory errors or warnings themselves, just a sudden “exited on Signal 6” message,
followed by the memory status.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The server has 16GB of ram, and every time I run “opensipsctl fifo get_statistics all” the processes indicate plenty of available private and shared memory. Server is CentOS 6.6, running OpenSIPS 1.11.3, with 16GB of RAM.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">No changes were made to the system before these events started happening, although afterwards I did recompile OpenSIPS to add in the DBG_QM_MALLOC compile option per the TroubleShooting instructions.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This system has run stably for about two weeks, and then this suddenly started happening. Has anyone experienced anything similar?<o:p></o:p></p>
