This error has nothing to do with the pagefile. The "storage space available" it speaks of is either kernel pool or desktop heap - remember, only the memory manager knows about RAM and the page file, not a running process; they only see 2GB of VA. This isn't a memory manager error speaking of VA, it's an error of pool or heap. I seen errors that remind me of that before when I disabled virtual memory. (pagefile) Especially PCs with limited RAM. Looks like that, to me, especially if that error code occurs with all services. Those conditions may cause all future memory allocations to fail. Because of all memory spaces running out, because it can't page any more to HDD at all!
