Hi Chris, I don't need 120 concurrent connections. The problem arises from subsequently opening connections and the script is a way to simulate the problem: the first 100 connections e.g. open up fine; then the next 5 mess up; then the next 7 are good to go again etc... I'm using the basic PHP php_mysql.dll driver. I've used MDB2 from PEAR as well: same result. I think both of these use the C API, and not the ODBC-driver.

Well to be honest my question would be why do you need 120 connections in one script? > The solution that's mentioned is to enable connection pooling, yet since I'm > using the x64 edition, that doesn't work for me. Why doesn't it work for you? What package were you going to use for connection pooling?
