Though this is not likely to solve the problem, try adding the following two lines at the beginning of the script (even before you query the database and do all your logic) ignore_user_abort(true); set_time_limit(0); If this solves the problem you should read this http://ar2.php.net/info and this http://ar2.php.net/manual/es/function.ignore-user-abort.php carefully and then choose more rational settings. PHP has a default execution time of 30s. However, this is not likely to solve the problem as execution time should not be affected by streaming and we are assuming the user/browser is not aborting the connection. On the other hand you could support download resuming (it involves some tricky headers and if you are willing to dig deeper into this read the manual notes at http://ar.php.net/manual/es/function.header.php). But this won't solve your problem... at least for IE as it doesn't support resuming :(. You need the log files to know exactly what the problem is. And, even if you are not solving this issue using compression as a workaround, you may also want to add at the beginning of the script: ob_start("ob_gzhandler") Or... you can use "zlib.output_compression" INI setting in an .htaccess file or in php.ini. Compressed files will require more server processing but will download way faster. ob_gzhandler and zlib compression are transparent to the end user, so they will think they've got the uncompressed file, no need to gzip the files programmatically.
