 Description  « Hide
An application creates four connections in four threads to the same database using Local protocol.
Sometimes it gets an exception with a message "connection lost to a database" when particular thread tries to establish a connection.
It does not happen if TCP/IP connection is used, for example.
As well It does not happen if older version of fbclient.dll (from FB 2.1.3) with Local protocol is used with FB 2.5.0 server.
