My database was down but Lxguard was unable to restart it

[Spacedust]

I got tons of these:

Host: backup.xxx.pl
Date: Aug-12 01:23
Port: 3306
Action: sh /script/restart-mysql --force >/dev/null 2>&1

When I restarted with /etc/init.d/mysql restart it worked instantly. Why ?

I'm using MariaDB.

Configure is not 'normal' setting, except '1000' so high. What's about log inside /var/lib/mysql?.

[Spacedust]

The same for pdns today !

Kloxo was executing:

Host: xxx
Date: Aug-17 08:19
Port: 53
Action: sh /script/restart-dns --force >/dev/null 2>&1

but server was still down. When I just runned /etc/init.d/pdns restart it instantly restarted !

It seems Kloxo does not have permissions to run these scripts...

Not lxguard but watchdog.
