upload large files troubles

hi! I have apache2 + php5. I need to upload large files. I found out, that file is uploaded always. But: - if the file is less than 167 MB all is OK, then I tryed larger files - from 191 MB up, files are uploaded, but php script, which handle the operation is "like" not executed. I always get blank (clear) page (f.e. echo "hello"; does not work!), so I can not let users know, that upload finished OK. Here is part of my php.ini file: max_execution_time = 70000 max_input_time = 70000 memory_limit = 16M post_max_size = 900M upload_max_filesize = 900M default_socket_timeout = 80000 ....I think, these are all interested parts in this problem. Thanks.
