I've got a multi tenant system with about 300 databases all with the same model.
I use entity framework 5.0 with MySql .Net Connector 18.104.22.168 (currently the latest)! In this system there are 5 Windows Services and 1 Asp.Net WebSite who access these databases. The Problem is somewhere in the services.
Every 5 minutes each service will go through all databases and do stuff for each database. Every now and then I get the following error from entitiy framework:
The underlying provider failed on Open. -- Authentication to host 'xxx' for user 'yyy' using method 'mysql_native_password' failed with messeage: Reading from the stream has failed.
My connection string is dynamically built by
cConnectionString.Server = "127.0.0.1"; cConnectionString.Database = sDatabase; cConnectionString.UserID = sUserName; cConnectionString.Password = sPassword; cConnectionString.UseDefaultCommandTimeoutForEF = true; cConnectionString.IntegratedSecurity = false; cConnectionString.PersistSecurityInfo = false;
Does anyone have a clue where I could start searching for the error?
I've found the same error here, but everything on my server is running in 64bit mode.
