Hello Tolga, 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 http://www.opensips.org/Documentation/TroubleShooting-OutOfMem .
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.
