i checked my /etc/chkserv.d/mysql file after chkservd don't getting to start mysql (but i got to start it using "service mysqld start") and found:

service[mysql]=x,x,x,/scripts/restartsrv mysql,mysqld_safe|safe_mysqld,mysql|root
(i use cPanel)

if I type "/scripts/restartsrv mysql,mysqld_safe" it won't work...

just with this line, does chkservd knows it should execute:
- /scripts/restartsrv mysql
- /scripts/restartsrv mysqld_safe

if so, there should be a problem with "/scripts/restartsrv mysql"
