The issue is the way how the server process is spawned, under circumstances it might not load the openssl extension. That's none of issue when openssl is compiled statically like it often might be done on linux. On windows it's always shared, so the solution is to ensure there's a suitable php.ini is laying around or explicitly passing a temporary php.ini to the spawnee and ensuring the openssl deps are on the path. Still stream_server_reneg_limit.phpt hangs, but sa you mentioned that being an issue. Lets see how it behaves further. Thanks for the help on this. Anatol
