Hey, if you will delete log files you can lost your working WEB server. Stop it, guys. You must not delete anything you did not create!
Just clean the big logs or configure logrotate. The simplest logrotate config below:
# Logrotate CWP
/usr/local/apache/domlogs/*.log {
compress
delaycompress
daily
missingok
}
/usr/local/apache/logs/*.log {
compress
delaycompress
daily
missingok
}
