Iot Gateway Omnicore OPC ua subscribe issue after warmstart

Hi!

Im running a RW 7.15.3 system with a OPC UA server running through IoT Gateway. I have an issue that the server is not triggering updates on my subscribed IO signal variables after a warmstart. There is some really weird issues that sometimes some of the signal subscription callbacks work, and after a restart/resubscribe of the OPC UA client application it works again. But sometimes I have to restart the whole OPC UA server in IoT gateway to make it work again. When I get it working, it works fine until another restart of the robot controller...
Any ideas? I'm considering switching to PC SDK communication instead.
