Hi All,

I have a connection from a central Ignition Gateway to a site Ignition Gateway via an OPC Server connection. About once a week the central OPC Server Connection changes state to fault and on the site Gateway I get the error messages shown below.  
To restore the connection I go to the central Ignition Gateway-\>OPC Server Connections and edit the connection. I set it to disabled, then change it back to enabled again. It connects and work well for another few days.

Has anybody else had this problem?  
What do I need to do to make it stay connected? or at least reconnect after a fault?

This sounds like something that was fixed in 7.9.8. There’s an entry in the change log about “improved handling of reconnections”.
