              There’s not enough context here to provide a meaningful response.  Where are you seeing this message?

                  Sorry for delay. The problem arises in MacosSierra. It's conventional http read from server retruning xml file. The message is in log with couple of other messages which follow:

                      OK, here’s how this breaks down:

                      • “TIC” expands to “TCP I/O connection”, which is a subsystem within CFNetwork that runs a TCP connection

                      • “Read Error” is pretty self explanatory

                      • “476” is a connection ID number within TIC; it’s not useful to you

                      • “0x60800018dc30” is a pointer to the TIC object itself; again it’s not useful to you

                      • “1” and “57” are the CFStreamError domain and code, respectively; a domain of 1 is kCFStreamErrorDomainPOSIX and, within that domain, 57 is ENOTCONN

                      In short, a TCP read has failed with ENOTCONN.

                      As the TCP I/O connection subsystem has no public API, you must necessarily be using it via some high-level wrapper (like NSURLSession).  What API is that?  Do you see the error manifest there?  If so, what’s does that error look like?

                          The problem is that even if I see error in system log, application works correctly (as it was in previous rel. of OSX), data is delivered and no error in debug. Thanks for explanation of this 1:57 code (TIC Read Error is definitelly selfexplanatory :-)). For app is used NSURLSessionDataTask

                          with completionHandler where is no error indication, errror == nil and no statusCode in NSHTTPURLResponse.
