[SR-Users] Kamailio 5.4.3 crash at SSL error

[Daniel-Constantin Mierla]

OK, let's see if pops up again.

Does Centos 7 ships both libssl 1.0.x and 1.1.x? If yes, then I noticed
immature libssl 1.1.x version being present typically in such cases
(early version of 1.1.x).

You can see which one was used to link the tls module with:

ldd /path/to/tls.so

Cheers,
Daniel
