Problem with SapPooledConnection

[jecojack]

Hello, I'm facing the following error when I try to call a bapi

SapNwRfc.Exceptions.SapException: SAP RFC Error: RFC_ABAP_RUNTIME_FAILURE with message: No roll memory of length 2353575936 available for event stack.

when I call:

public T CallFunction(string functionName, string connectionstring)
{
	ISapConnectionPool pool = new SapConnectionPool(connectionstring);
	ISapPooledConnection connection = new SapPooledConnection(pool);
	return connection.InvokeFunction(functionName);
}

Instead, using the following, it works...

public void CallFunction3(string functionName, string connectionstring)
{
	using (var connection = new SapConnection(connectionstring))
	{
		connection.Connect();
		using var someFunction = connection.CreateFunction(functionName);
		var result = someFunction.Invoke<SomeFunctionResult>(new SomeFunctionParameters
		{
			PROGRAMID = "RESULT",
		});
	}
}

Any ideas?
thx

Just another user here, but your initial generic function doesn't look valid - I would expect something like public T CallFunction<T>() that could return T. You also aren't providing any input parameters (and you are in the second example).

Additionally, creating a pool every time you want a connection kind of defeats the purpose - you want to have a pool of connections where you take and return connections so they can be reused. Otherwise, just create a normal connection.
