Hi,

 

The default configuration is not fit for load balancing.

 

You need do more for your server.

 

There's two solution for load balancing:

 

1 - set temp directory to a shared server , for example , \\sharedserver\sharefolder

 

2 - use database provider to store the temp files into SqlServer

your server may throw another error , but Silverlight can't catch it. you can check the SYSTEM EVENT for more
