Livecycle Connector to Sharepoint behind load balancer

[raymondng_gti]

In the environment of our customer, there is a load balancer in front of 2 sharepoint servers.

Then the PDF document is uploaded from the Livecycle server to sharepoint (via the load balancer).

However, occasionally it will fail to place the PDF to the folder specified, and placed on the outermost folder in sharepoint. 

May we have any hint to fix the problem?

Thanks.
