<p>Thanks for troubleshooting further.</p>
<p>Can you try with pre-loaded library workaround that was pushed to git master yesterday? Respectively:</p>
<ul>
<li><a href="https://github.com/kamailio/kamailio/tree/master/src/modules/tls/utils/openssl_mutex_shared">https://github.com/kamailio/kamailio/tree/master/src/modules/tls/utils/openssl_mutex_shared</a></li>
</ul>
<p>It looks like a side effect of not having the pthread locks initialized by libssl 1.1 with process shared option. If proves to work fine, then we can approach openssl project to introduce a way to allow setting the process shared option for locks.</p>
