Описание проблемы
У меня есть сервер, на котором запущен Debian 8.11, с сервером apache2, в настоящее время использующим PHP 5.6.
Я хочу перейти на PHP 7.3 и установил PHP 7.3 с apt(php7.3 php7.3-fpm php7.3-mysql php7.3-curl php7.3-json php7.3-gd php7.3-intl php7.3-mbstring php7.3-xml php7.3-zip php7.3-exif php7.3-apcu).
Я знаю, что смогу изменить версию PHP с помощью apache, запустив a2dismod php5 и a2enmod php7.3. Тем не менее, когда я выполняю тест конфигурации с sudo apache2ctl configtest, я получаю ошибку сегментации:
$ sudo apache2ctl configtest
Syntax OK
Segmentation fault
Action 'configtest' failed.
После некоторых проб и ошибок ошибка сегментации исчезает, когда я отключаю модуль SSL (sudo a2dismod ssl), но я хочу иметь возможность обслуживать веб-сайт по протоколу HTTPS, так же, как я делаю это в настоящее время в PHP 5.6.
Вопрос
Я не могу узнать, что я должен изменить в своей конфигурации SSLс обновлением с PHP 5 до PHP 7. Может ли кто-нибудь помочь?

apache2.conf
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.
# Global configuration
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.

# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#

# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the

#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>

# container, that host's errors will be logged there and not here.
