Hello,

there were some broken versions of openssl that didn't allow anymore to set custom memory manager. The only option is to upgrade libssl to a version that doesn't expose the issue. If you search on kamailio issues tracker on gihub.com, there should be one closed about this topic.

Cheers,
Daniel

for resolving have compiled openssl from 1.0.2j-fips to

openssl version

OpenSSL 1.0.2n  7 Dec 2017

Is this information enough to see what we are missing 

Will provide more info if needed.

Any help and suggestions are appreciated.

Regards,
