Re: close inactive client connection

hi John


I have no idea of what may be happening. The system opens a connection
and communicate normally. But after an idle time, it loses the
connection and new transactions return with error.

16/09/2009 13:39:14 - SQL Error: no connection to the server
16/09/2009 13:39:14 - SQL Error: connection not open


At this point he reconnects, the server creates a new connection that
behaves exactly like the previous one.
