Hello @amenella About four days ago Alpine is switched to used openssl instread of libressl. We also updated kamailio docker image `kamailio/kamailio-ci` to use openssl. Could you retest with current `kamailio/kamailio-ci:master-alpine.debug` docker image. Need to execute `docker pull kamailio/kamailio-ci:master-alpine.debug` before test.
This docker container supports creation of core files. If core files is generated ned to create backtrace using `gdb`. To get core file need start container using commands like ``` docker run -it --entrypoint=sh kamailio/kamailio-ci:master-alpine.debug kamailio -DD -E ```
