Hi Allan Did you ever find a resolution for this?
We started to get the exakt same issue you describe a couple of month ago on a customer when upgrading from v13 to v17.0 HF2. 4D then told us to update 17.3 HF2, still same problem. Customer is running Windows 10 clients and Windows Server 2012. We use 32 bit client and 64bit server. The environment was the same when running v13 where did not have this issue. Server can be running from 1-2 days until almost 2 weeks before it happens. We are currently using the legacy network layer and we are now about to change to the "new network layer" (again recommendation from 4D). We are quite desperate to find a solution for this. Any details you can share would be greatly appreciated. Anyone else having the same issue?
