<p>I have updated opensips to v2.1.1 Git Rev. <a href="https://github.com/OpenSIPS/opensips/commit/4c775f2b63c4e7def59654cd70f30934d8e08e10" class="commit-link"><tt>4c775f2</tt></a>. I still have crash through frequency is a bit reduced now, previously it was crashing on every call, now it crashes every 2nd or 3rd call. I see two core dumps, here are their back traces.</p>
