I logged a DTS case with Apple and their technical support guy looked at the code but didn't find any problems. He asked me to log a bug on Apple. I have logged a bug but I haven't got a single reply on the ticket. It has been more than two months and we are also stuck because of this

Hi Matt, Sure, I will check the transmission size for TLS connections. Regarding FilterDataProviders, your comment suggests to me that FilterDataProviders may not be a good solution for monitoring data from the start of the connection to the termination of connection. If this is true, what should be used to monitor traffic for the entire duration of the connection? Regards
