Why do my ODBC-ODBC Bridge connections drop?

The Easysoft ODBC-ODBC Bridge server has an inactivity timer, which, by default is set to 7200 seconds. If a client connects to the server and does nothing for 7200 seconds (2 hours), the server terminates that connection. This can cause problems with applications that offer persistent connections. For example, PHP's persistent connection feature attempts to continue to use a terminated connection.

The timeouts are there to stop unnecessary connections building up. You can turn off the inactivity timeout by setting it to 0. Alternatively, increase the timeout.
