Hi Stefan,

You might find the following blog post useful:

It looks as though the socket is being shut down (likely being killed as inactive at the OS or firewall level). Networks can be problematic, even when connections are not left idle for extensive periods of time (2h qualifies). You can try to track this down at the network level, but it's far better to ensure your application (or more appropriately, connection pool library) is doing periodic maintenance on unused Connections to ensure they remain viable.

Hope that helps,
