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>
