Solution 1 : This problem occurs when physical RAM Plus Virtual RAM (usually created on hard disk) together are not sufficient to take care of the currently needed RAM size, or this error is arise. This usually happens when some fixed upper limit for Virtual Memory has been set. To solve this problem, you can either upgrade you physical RAM on your computer (recommended), or you can set the Virtual Memory to system managed size or you can do both.
