SYMPTOMS
The following error message is logged in the SoftGrid Virtual Application Server log file, sft-server.log:

41503 &quot;Invalid raw data request:  bytes.&quot;



CAUSE
This issue occurs if the value of the Max Block Size setting of SoftGrid Virtual Application Server is smaller than the value of the Max Block Size setting of the .sft file.



RESOLUTION
To resolve this issue, increase the Max Block Size setting of SoftGrid Virtual Application Server so that it is equal to or greater than the Max Block Size setting of the .sft file. To do this, follow these steps in SoftGrid Virtual Application Server.  Use a text editor, such as Notepad, to open the Sft-server.log file. Locate the &quot;Invalid raw data request&quot; line. For example, locate the following line:

[0000-00-00 00:00:00.000]  3368 1512 SW_CacheHandle::GetRawData - &quot;Default Provider&quot;   .sft 2 41503 &quot;Invalid raw data request: 671004 bytes.&quot;

Alternatively, use Sequencer to open the .sft file, and then click the Properties tab. The value of the Max Block Size setting appears under Dir Map General. This value is in bytes. Note the size of the &quot;Invalid raw data request&quot; setting. In this example, the size is 671,004 bytes. Convert this value to kilobytes. For example, convert 671,004 bytes to 672 kilobyes (KB). Start the SoftGrid Management Console. Expand SoftGrid Systems, expand  , expand Server Groups, and then expand Default Server Group. Right-click SoftGrid Virtual Application Server, and then click Properties.</li> Click the Advanced tab.</li> In the Max Block Size (KB) box, type 672.

Note The default value of the Max Block Size (KB) setting is 512.</li> Click OK.</li> Stop, and then start the SoftGrid Virtual Application Server service.</li></ol>
