Get blocked by this in SOSSE 9.2 Configuration Page.
I've got an issue that wanted "max worker threads" changed. (effecting the change made no difference)
I then went to change the value back to 0 (Unlimited/SystemDefined) when I was blocked with an error "value is less than minimum". (128 on my server)
In most cases the configuration options default to 0 as an Unlimited/SystemDefined value - despite and minimum value that may be set.
-- back to scripting it.
