System hangs after IncreaseUserVa change on Windows 7 64-bit

-1

By mistake, I applied the IncreaseUserVa 3072 on a Windows 7 64-bit:

BCDEDIT /set IncreaseUserva 3072

After that, the system is getting hanged when I start an intensive Matlab code.

I tried to revert the change using both:

BCDEDIT /set increaseUserva 2048

or

BCDEDIT /deletevalue increaseUserva

But, I get to the same problem when I run the Matlab code.

When I check bcdedit/enum all, it does not contain increaseUserva, after /deletevalue command.

Any idea?

You were right bcdedit /set IncreaseUserVA 2048 (should) fix your problem. Have you restarted your computer? – Christian – 2013-10-25T15:27:10.197

Thanks. It seems BCDEDIT /deletevalue increaseUserva is fine. – imriss – 2013-10-26T03:33:13.907

BCDEDIT was working fine. The correct command is: BCDEDIT /deletevalue increaseUserva. The problem was with another change that I made at the same time; in the Matlab code, I added a try/catch around the command that was requiring a large amount of memory. Apparently, this was leading Matlab to commit a large amount of memory (40 GB in Resource Monitor was observed). Now, I replaced try/catch with an if and it works.
