Hi, You are receiving an additional response to Describe command that was previously received completely ( CSeq: 4). Your setup sent with CSeq: 5 but response came to CSeq: 4 - Handler for this was already completed. Try to implement a timeout handler - I had an issue with different vendor of cameras that were messing with sockets and it helped(although I dodn't received 408 code but yes I was receiving unexpected responses). I then raised the idea of setting timeout value for each command but Ross's suggestion was to run a custom timer (via Live library) and track timeouts - I implemented this and this worked.
Best regards, Alexander.
