How to create new item or trigger for template which is used by thousands of hosts

[terry.lu]

a template is used by so many hosts that i can't add or modify item/trigger for it.

I try , just get no reply. It seems it is kind of timeout?

Any good idea to deal with this? I don't want to do massive update on database directly.

Thanks

What you mean that you can't add or modify item/trigger?
