Error updating to 1.6.1

[netsysadmin]

Hi all,

I currently have Zabbix 1.6 installed.
On trying to upgrade to 1.6.1 by running the following command:
cat patch.sql |mysql zabbix -u root -p
I get the following error message:
ERROR 1060 (42S21) at line 1: Duplicate column name 'esc_period'

Does anyone have an idea what's wrong?

Thanks

What? One doesn't have to run ANY patches in order to upgrade from 1.6 to any of 1.6.x!
