I am using 7.8.0 and am running into a VERY serious intermittent problem. Every once in a while, all my objects with PLC tag bindings show a gray overlay, and my OPC-UA server still has a status of Connected. The only fix is to disable and re-enable the OPC-UA server.
Below is my wrapper.log which includes the time period the issue happened, up until I got the system working again (which is done by disabling the OPC-UA server and re-enabling it). I am not sure if any of these entries tell me anything useful, but it is a system that runs 24/7 and I won’t always be available to ‘fix’ it.
Is this a known issue in 7.8.0? If so I can upgrade to 7.8.3 without any issues, but I would need to know that this was specifically addressed and resolved in 7.8.3 (we can’t really do an upgrade and just “hope it fixes it”).
