Hi all,

Today I upgraded Kamailio to 5.4.5 and a random crash was just reported in our crash monitoring script.  Below is the output of the crash:

Is this crash due to libcrypto or mysql client?
Currently I have the following mysql client installed on the kamailio instance:

ii  libmysqlclient20:amd64               5.7.34-0ubuntu0.18.04.1             amd64        MySQL database client library

ii  mysql-client                         5.7.34-0ubuntu0.18.04.1             all          MySQL database client (metapackage depending on the latest version)

ii  mysql-client-5.7                     5.7.34-0ubuntu0.18.04.1             amd64        MySQL database client binaries

ii  mysql-client-core-5.7                5.7.34-0ubuntu0.18.04.1             amd64        MySQL database core client binaries

ii  mysql-common                         5.8+1.0.4                           all          MySQL database common files, e.g. /etc/mysql/my.cnf
