Hi David, Do you have a managed switch on this network?, it is possible for a switch to close a connection with no traffic, which could also result in this message.
The usual wisdom dictate having the timeout set to less than the switch/router timeout to prevent the port closing without the application knowing this.

I searched 4D Tech on gmane, read the docs on keeping the connection open, but after about 15 minutes of idle time, with no user activity, we get this error message (above and below). A network semaphore with a 300 ms timeout is crashing. When we remove the network semaphore, we crash on a QUERY in a different method. This exact same error occurs on our client’s network. I need help fixing this one. A serious error occurred while a request was being sent to the server. You should quit or restart the database as soon as possible.
