Re: .Net connector suddenly fail to connect

[Francois Carabin]

Hi Gabriela,

All tests are on Windows platform:
MySQL Server 5.6.27 (x64) on Windows Server 2008 R2 SP1.
Tests programs also run on Windows Server 2008 R2 SP1.

Using Wireshark we detect a lot of problems during TCP transmission on port 3309 (used for DB connection).
Connection works with C# connector changing "Jumbo Packet" size to 2000 (original value was 1500, it is the standard) on the network adapters (on the both servers) but we still facing the problem with other requests to on the database.

So it is a network problem. Unfortunately, we do not control all the network and the firewall managing the subnets .....

By the way, do you have an explanation for different packets size during the connection to the database between the C# connector and the C connector (not C++ I make a mistake in my first post) ?

Best regards,
