When TRCC fails to connect we see in ADH.log (3.4.1) the error
</local/jenkins/workspace/TREP34XCore_Release/OS/OL7-64/esdk/source/esdk/Cpp-C/Eta/Impl/Transport/rsslSocketTransportImpl.c:694> Error:1002 ipcRead() failure. System errno: (0)
I take it that "jenkins" is one of your developers and ask if this error can be updated in future versions
