                                        The crash seems to be in the
                                        memory manager, most probably
                                        because of memory corruption. To
                                        troubleshoot such issues you
                                        need to compile-in the memory
                                        debugger - see <a href="http://www.opensips.org/Documentation/TroubleShooting-OutOfMem" target="_blank">http://www.opensips.org/Documentation/TroubleShooting-OutOfMem</a>
                                        .<br>
                                        <br>
                                        Using memlog=1 + memdump=10 you
                                        should get a lot of logs related
                                        to mem ops, including a final
                                        report + abort() when the
                                        corruption is detected.<br>
