Hi, I am connecting to the Linux server, but some times i have issue below. It is happening by the second connect. After starting the application, first connecting is right (without error ) but second not. Another connections to the server is right (over 200 connections).

The app is a java service running on Linux, which is connecting to another servers.

Thank you for help or some information about Error logs.

Error :

Are you reusing clients/connections/sessions?

[MilosSvrcek]

What do you mean reusing? Example:
I create connection on the server and do some things, then I close connection. After one hour I have to create connection and do some things again and close connection. So after every time I close connection, I have to create them again. SMB2 have some cache, which one has information about connection?

[hierynomus]

You're reusing the connection to re-authenticate. However you should be getting a new connection from the SmbClient.

Does that work?

My case is, I closed the connnection before my operation (authenticate or connectShare) finish.
