Even simple scripts like the one below *WITHOUT AN MSSQL QUERY* when reloaded repeatedly quickly will either cause an access violation error or make php get stuck (i.e. CPU meter will show cycles being consumed even though all pages have finished loading - note: I am using dual processor under Win 2000 Pro).  The only changes to the php.ini-optimized file were register_globals=On, magic_quotes_gpc=on and extension=php_mssql70.dll

Simply loading php_mssql70.dll seems to be the culprit as without it the phenomena does not occur. This is probably the cause of the other reported MS SQL bugs as well and seems to have nothing to do with running a database query at all.
