I'm new user learning to use Iris and Ensemble. I'm trying to set up a TCP interface to send delimited data from Ensemble to another interface engine. I created File.PassthroughService to pick up the file and send the data to TCP.Framed.PassthroughOperation. The framing is MLLP and SSL configuration used. It is able to process small files around 50kb. When I drop a larger file such as 5mb, the operation is not getting the ack within the 60 sec timeout.
