I just recently setup my WordPress 1.5.2 system on an hosted environment (Network Solutions) and everything is working fine. But for whatever reason, and time to time, me or any user of my blog will receive the Error establishing a database connection error. Just by hitting F5 (refresh) then it's usually ok (but quite annoying). I checked through the support section, but couldn't find anything on this error other than the initial setup problems... Anyone has any idea?
