Uploading files up to 150MB onto server

[Rosie Chua]

Dear all,

I am running an online file management server that allows web clients to
upload files from a webform to the web server.

Using the code
"filename.PostedFile.SaveAs(fullPath);"
I have no problem uploading file with size up to 25MB, but the page starts
to create problem with any size above 25 MB - the error message displayed is
"Server Unavailable" or occasionally it just dies off.

I am running the web server using ASP.net framework 1.0 developed using C#

In the Application Log of the machine's event viewer, I get these message:

Event Type: Error
Event Source: ASP.NET 1.0.3705.288
Event Category: None
Event ID: 1003

Description:
aspnet_wp.exe (PID: 2108) was recycled because it was suspected to be in a
deadlocked state. It did not send any responses for pending requests in the
last 180 seconds.

Description:
aspnet_wp.exe (PID: 1532) was recycled because memory consumption exceeded
the 306 MB (60 percent of available RAM).

I'd set the following value on Web.Config, but it still doesn't work:
<httpRuntime maxRequestLength="153600" />

Anyone know how to go around this problem? The uploaded file size could be
up to 150MB in size.

Cheers

I suspect that the upload is gobbling up the server's memory because the
content isn't being flushed to disk as it streams. You might want to
investigate a commercial upload component for this kind of task:

You need a script or component that accepts the uploaded file and streams it
to disk, rather than holding it in memory first. It would be fairly easy to
write such a thing, using basic TCP sockets to accept the HTTP request, then
the IO stuff to write it to disk.

Sorry, I don't have the time to write the component for free. Besides, you'd
learn a lot more by doing it yourself. I suggest doing some tutorials for
socket programming on the web, then some for writing files. Combine the two.

Russ,

Thanks heaps for your reply. Can you please provide more details, or the
sample code? Thanks again.
