Hi guys, i solve this problem, the problem was a error_log file locate in " /usr/local/apache/logs/error_log "
So if you have problem with space in partition " /dev/mapper/vg_server-lv_root " , you can make a cron job using this command command " echo '' > /usr/local/apache/logs/error_log "  
like in this picture: 

in this picture i set to empty that log at every 1 minute, you can chose the time you whant. 
I hope it will help you
