Using X-Accel-Redirect certainly is a better way regardless, but I don't know of any issues with daemon mode being able to serve up such a large file. Are you using wsgi.file_wrapper to optimise serving the file, or using your own mechanism for streaming. EIther way it probably doesn't matter if you use wsgi.file_wrapper or not as it isn't the daemon process which is failing. That you get the error that cant write data suggests the Apache server child process which is proxying the request to the daemon mode process has likely exited, failed in some way, or the client connection has closed which has result in connection to daemon process being forcibly closed as well. Can you actually reliably reproduce this issue? Graham > On May 12, 10:33 am, btimby <[email protected]> wrote: >> I am streaming a file from my mod_wsgi application to a client.
