Failed to find an available port between <DebuggerMinPort> and <DebuggerMaxPort> to listen for connections from the client <PowerCenter Client machine name>.
The Integration Service could not find an available port for Debugger connections.
Stop other Debugger sessions or wait for those sessions to complete before you restart the current Debugger session.
Increase the DebuggerMaxPort value to provide additional ports for Debugging on the Integration Service.
