I have strange messages in the console related to an OPC DA server with OPC COM. I have plenty of logs related to COM Subscription.

I have stopped all clients on the gateway and I have always these logs merssages

I have disabled all the others OPC DA server connections and I have only enable the one I suspect to cause problems

Every day I must stop/restart the gateway, it seems there is an out of memory error in Java

I joined the logs I have set COMSubscription and COMServer in DEBUG mode.

However, the OPC server is working because I can see the tags in the designer and the values are OK  
( I have about 2 or 3 thousands tag and the values are OK)

The opc da server is Devio from technilog, a french well known company
