Has reached the '1' for the maximum number of administrator connections, thus unable to establish a connection, before establishing a new connection, must go through the cancellation or the end of the process to remove the dedicated administrator connection, existing [client: 127.0.0.1]

Server crashes, recently discovered log last one is this, then I put the TCP connection is closed, there is the problem? Is there a big help see what reason? Not very grateful!

CodePudding user response:

I just simulation and connected to the connection repeatedly, this is because there are DAC and MSSQL mechanism is a only one DAC connection exists, after connection error will be reported to The Times,

So you need to check your machine code or business, whether to have try to connect, has been using DAC

Find it off, can't find the error it doesn't matter, for it does not affect business use
