Is there any addon that allows disable options as the load of the hosting?
phpBB can be configured in the minimum load to search, or disable the entire forum if the load is very high.
I am needing something, and can not find it.
It really sounds like you need to look at a different hosting package or a new host. By disabling forum features you not doing your forums quality any good. People will get fedup with features working then not working and leave.
