12679	VBox suddenly will not start, with error message.	nijineko		"Macbook 5,2; OS X 10.6.8; VBox v4.3.6. VBox launches w/o error. Upon start of VM (Windows 7) the following error is received:

Failed to open a session for the virtual machine Astarael_w7.

Failed to map a memory object. (VERR_MAP_FAILED).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

Only recent change to machine is a change to the RAM from 2GB to 6GB. Prior to change in RAM, worked without error, if somewhat slow. Have perused forums, discovered proposed workaround of removing VBox* files from the Library directory with Terminal and reinstalling the latest version of VBox, however, this did not succeed in resolving the problem.
