Describe the traffic that generated the bug The bug occurs with TLS and clusterer modules together with OpenSSL during Opensips startup.

To Reproduce

Setup a running PostgreSQL server (I didn't try with MySQL). Setup a 1 node cluster by populating the clusterer table. Start OpenSIPS with this configuration file :
