[SR-Users] segmentation fault when mongodb & tls enabled. ( kamailio 4.3.2)

Thu Oct 1 17:00:27 CEST 2015

Why the backtrace doesn't show the timer function pointer? Am i missing
something?

Im building the mongo-c-driver as below
get the tar file from
https://github.com/mongodb/mongo-c-driver/releases/download/1.1.11/mongo-c-driver-1.1.11.tar.gz
run the rpm build using the spec file attached.
To disable the ssl, i have modified  '--enable-ssl=no' in the configure
 command in the spec file
%configure --disable-static --disable-silent-rules --enable-debug-symbols
--enable-man-pages --enable-ssl=yes --enable-sasl --with-libbson=bundled
--enable-optimizations

In kamailio im using db_mongodb. I'm getting same error  for ndb_mongodb as
well.

Please find the kamailio config scripts.
