Source: apache2 Version: 2.4.25-3+deb9u3 Severity: normal Dear Maintainer,
On a fresh install of apache2, we have theses defaults : # apache2ctl -S VirtualHost configuration: *:80 172.17.0.2 (/etc/apache2/sites- enabled/000-default.conf:1) ServerRoot: "/etc/apache2" Main DocumentRoot: "/var/www/html" Main ErrorLog: "/var/log/apache2/error.log" Mutex watchdog-callback: using_defaults Mutex default: dir="/var/run/apache2/" mechanism=default PidFile: "/var/run/apache2/apache2.pid" Define: DUMP_VHOSTS Define: DUMP_RUN_CFG User: name="www-data" id=33 Group: name="www-data" id=33 Mutex dir is /var/run/apache2/ not the historical /var/lock/apache2. I had got some Mutex problems with a EC2 official stretch image, reverted the /var/lock/apache2 value (uncomment Mutex line in apache2.conf) and no more problems appeared.
