Hi , 


I am facing an issue with OPC HDA interface where the data is only being sent for initial 30 minutes or less after starting the interface. After few minutes,  interface stops sending the data while the service remains in running status. 


If we restart the interface at this point,  history recovery runs successfully and updates all the missing data and then the issues repeats again. This behavior is observed to be repeating and no errors were being logged in PI SDK for further analysis. 


Issue from DCS end has been ruled out as the same system has been sending data to other OPC HDA  interfaces without any issues. 


Please let me know if this has been observed anywhere/ How to troubleshoot .
