Description:
A known upstream bug in libcap-ng 0.7.9 is causing segfaults in apache. This is a known and identified upstream bug: see links below. This happens whenever apache httpd reloads its configuration which is once every few hours. This is rendering the apache server useless. The bug only happens when libcap-ng is used as a dependency of php modules. In my case through php-intl, but there are reported cases where other php modules are involved. This bug has already been solved in upstream version 0.7.10. I have confirmed this by rebuilding from the existing PKGBUILD with upstream version 0.7.10. I have no more segfaults for 3+ days now, even after manually triggering a configuration reload. Before, it would instantly segfault on a configuration reload. Additional info: * package version(s): libcap-ng 0.7.9-2 * httpd log file: [core:notice] [pid 3238] AH00051: child pid 4114 exit signal Segmentation fault (11), possible coredump in /etc/httpd * journal log entry: systemd-coredump[714225]: Process 714223 (httpd) of user 66977792 dumped core.

Send reload command: systemctl reload httpd |
