Dear Greg,

Are you sure you have enough memory? Error itself seys:
tls: openssl bug #1491 (crash/mem leaks on low memory) ...

So you need to check config.yml options you have:

As Kamailio is trying to allocate all necessary memory on start:
allocated = children * pkg_mem (Mb) + shm_mem (Mb) + internal kamailio
threads/children.

So, if free RAM is not enough to start -> crash. It depends on X and Y
you have. I believe you have default pkg_mem and shm_mem values.
