    Hello folks,
    I'm new to this forum, so I hope that you will find some time to help me.
    Lately, I have issues with Apache, from time to time its stops by itself so I must start it manually.

    This is a state when it happens:
    This is /var/log/apache2/error.log:
    I disabled SSL Stapling in /sites-enabled/000-ispconfig.vhost and /sites-available/ispconfig.vhost (SSLUseStaling Off) , but I get same error.

    Please can you give some advice. Did anybody had the same problem?

    Greets,

    Can you find any more related info in /var/log/syslog, around that time?

    Hi, Th0m
    tnx for the reply :).

    In syslog.1 around that time, I can only see few CRON jobs, but maybe I missed something. Just one note, on line 3344 there is a notification "NameVirtualHost has no effect.... /etc/apache2/sites-enabled/000-ispconfig.vhost:7" which I found and comment in the file so it doesn't appear anymore.

    These are the lines from syslog.1 in that time:

    Maybe your system was out of memory?

    Hi Th0m,

    I don't believe it's memory since the VM is allocated 20 GB of RAM. Also, the server hosts 14 sites of which only two could have higher traffic than usual.

    Hi Taleman,

    yes, the system is ISPConfig on Debian 8 Jessie. The only changes I made were:
    commented line 7 NameVirtualHost*:8080 and line 90 SSLUseStapling Off in files /etc/apache2/sites-enabled/000-ispconfig.vhost and /etc/apache2/sites-available/ispconfig.vhost.
    Code:
     1 ######################################################
      2 # This virtual host contains the configuration
      3 # for the ISPConfig controlpanel
      4 ######################################################
      5
      6  Listen 8080
      7 #NameVirtualHost *:8080
      8
      9 <VirtualHost _default_:8080>

     16       SetHandler None
     17     </FilesMatch>
     18   </Directory>
     19   <Directory /usr/local/ispconfig/interface/web/>
     20     <FilesMatch "\.ph(p3?|tml)$">
     21       SetHandler None
     22     </FilesMatch>
     23   </Directory>
    Code:
     90     SSLUseStapling Off
     91   SSLStaplingResponderTimeout 5
     92   SSLStaplingReturnResponderErrors Off
     93   </VirtualHost>
    The reason for these changes is due to the following logs:
    Code:
    hosting apache2[6698]: Starting web server: apache2AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/sites-enabled/000-ispconfig.vhost:7
    Code:

    I don't know if it's related to your problem, but Debian 8 isn't supported in current ispconfig versions.

    Hi Jesse,

    well, my current version of ISPConfig is 3.2.4. But problems started before the update, I think in version 3.1.14.
    These are the new moments:
