Description Stefan Gohmann univentionstaff 2015-02-12 20:35:21 CET 
This happens on UCS:
 https://issues.kolab.org/show_bug.cgi?id=2050

If the kolab php modules are loaded, a apache reload results in a apache crash.

As a first workaround the apache init script should recognize this situation and restart the apache, for example:

  if $APACHE2CTL graceful $2 ; then
    log_end_msg 0
    if ! timeout 1 apache2ctl status >/dev/null; then 
       pkill -9 -f '^/usr/sbin/apache2 -k'
       $0 restart
    fi
  else
    ...
Comment 1 Stefan Gohmann univentionstaff 2015-02-13 07:25:48 CET 
The apache is now killed and restarted if a reload fails: r14378 + r14379

I've also added two basic apache tests to ucs-test: r58035
 - 01_base/83apache_configtest
 - 01_base/84apache_reload

This update will be released as erratum for UCS 4.0-0 and UCS 4.0-1. Since we added the Debian 7.8 update including a new apache package to UCS 4.0-1, this upgrade will include the Debian 7.8 apache upgrade for UCS 4.0-0.

YAML: 58034
