Hi,

I have a sharepoint 2007 app on IIS 6.0 windows server 2003 , and I want to upload files with it using webservice.the app upload file on session and after clicking on sendbtn it send created datatabe to webservice.

I checked my app with a file with size 9MB and it worked fine, but when I want to upload a 40MB file it returns an error when send file on sendbtn_click

Exception of type 'System.OutOfMemoryException' was thrown. 

 

I've set both my sharepoint web confing , so I can upload files on session with no error:

<httpRuntime executionTimeout="30000" maxRequestLength="2000000" />

I did that setting on my webservice too but  its not working.

this app works on my test server very well , but  on the customers server its not working.

I also changed the AspMaxRequestEntityAllowed on  Metabase.XML to

AspMaxRequestEntityAllowed="204800000"

I also changed     AspBufferingLimit="41943040" 

and I restarted my iis several times but the problem still exists:(

please help me

 

-----

I should add that my webservice will upload files on sqlserver 2008 R2

Hi,

check your application pool properties : do you have memory limits defined?

Or maybe it could be in the machine.config; there is a memorylimit attribute too.

 Hi fab,

thanks for response. I've checked my application pool:

maximum used memory (megabyte) is set to 1000

and maximum virtual memory (megabyte) is set to 1700

is there any thing that can cause a problem?

 Hi Steve,

Thanks for response,  I've just read the article, but the problem is not like mine.

I'm not using sharepoint lists and I'm not running crowl, also I've restarted my iis several times and nothing changed.

 I wondered! I've just checked the machine.config file, it has no memoryLimit on it. microsoft said that the default value is "60"(percent), So I've added memoryLimit="60" to the machine.config and restarted the IIS, and it worked!!!! now I can upload a file up to 100MB but when I tried to upload a file with 109MB it returned the error below:

 The underlying connection was closed: An unexpected error occurred on a send

any Idea?

What is the status code in the IISLogs?  What is the upload limit on your web app?

 Dear Steve,

Thanks alot for responce.I have no upload limit in my code, also I've set the web config of my web service to accept request with 2GB in it's web config...

<httpRuntime executionTimeout="30000" maxRequestLength="2000000" /> 

is there any other setting in my app that can probably limit my upload size?

and I'm seeking for my IISLog and I will update ASAP...

 Dear Steve,

I cant find the status code... can you help me?

Also I've find out that the problem is between my Presentation app and the webservice... because the webservice didn't raise any exeption...

Hi,

To find the status code from your log file.

Also I've find out that the problem is between my Presentation app and the webservice

 

You mean the problem occurs when your Presentation appliction calls the webservice?

 Hi,

Yes, I happens when UI calls the WebService.

and also it is ok when the file is 99MB... so i think the 100MB is the threshold for microsoft IIS.
