The timeout period elapsed prior to obtaining a connection from the pool

[Peter Haas]

Hy together,

In my application recently I got this errormessage
"The timeout period elapsed prior to obtaining a connection from the pool"

The application runs about 20days. Then this message occurs.

Does anybody know wherre this message comes from?

my source code:
OPEN connection:



mydbConnection = New MySqlConnection()
mydbConnection.ConnectionString = "server=" & ServerAddress & "user id=" & UserName & "password=" & UserPassword & "database=" & Database & "Allow User Variables=True"
'mydbConnection.ConnectionTimeout = 1
mydbConnection.Open()
mydbCommand = New MySqlCommand()
mydbCommand.Connection = mydbConnection



mySQL Request:
ConnectionPing = mydbConnection.Ping
'wenn keine verbindung besteht, dann öffne sie
If mydbConnection.State <> System.Data.ConnectionState.Open Or ConnectionPing = False Then
mydbConnection.Open()
