I am seeing "Segmentation fault" when starting apache2 in debug. When I do
Code: 
 # /usr/local/etc/rc.d/apache22 restart
Performing sanity check on apache22 configuration:
Syntax OK
apache22 not running? (check /var/run/httpd.pid).
Performing sanity check on apache22 configuration:
Syntax OK
Starting apache22.
and everytime it restarts showing "not running" and indeed not running in netstat or top. Error log has only this:
Code:

Debug start
Code: 
 # httpd -X
Segmentation fault (core dumped)
dmesg
Code: 
pid 58551 (httpd), uid 0: exited on signal 11 (core dumped)

P.S. Maybe it is related, server on ZFS.
 
Found what causing fault - a PHP module. After commenting
Code: 
#LoadModule php5_module        libexec/apache22/libphp5.so
apache2 started.
Also if execute:
Code: 
 # php -v
Segmentation fault (core dumped)
PHP version installed - php5-5.4.21

Update: tried PHP 5.5, it works with Apache, but doesn't support APC, so need PHP 5.4.
