Hi,
my application based on WCFService (NET 3.5) installed on machine connected (Windows Server 2003) to a Microsoft SQL Server 2005. Randomly generates this error:

System.ObjectDisposedException: Safe handle has been closed at System.Runtime.InteropServices.SafeHandle.DangerousAddRef (Boolean & success) at SNINativeMethodWrapper.SNIPacketReset (SafeHandle pConn, IOType ioType, SafeHandle packet) at System.Data.SqlClient.TdsParserStateObject.WriteSni () at

seems to be generated by improper management of connections between c # / sql server, how do I catch it and fix it. It occurs only on production environment.
