SYMPTOMS
The following error message is logged in the SoftGrid Virtual Application Server log file (Sft-server.log):

41486 &quot;Invalid chunk size:  bytes.&quot;

Note &quot;Invalid chunk size&quot; is incorrect. The message should read &quot;Invalid block size.&quot;



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



RESOLUTION
To resolve this issue, increase the Max Block Size value in the SoftGrid Virtual Application Server to be equal to or greater than the Max Block Size value in the .sft file. To do this, follow these steps:  Open the Sft-server.log file by using a text editor such as Notepad. Locate the &quot;Invalid raw data request&quot; line that resembles the following example:

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

 Note the size of the &quot;Invalid raw data request&quot; (in this example, the size is 671004 bytes). Round the size up, and then convert the size to kilobytes (KB) (in this example, convert the size to 672 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> For Max Block Size (KB), type 672.

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