That sounds about right. To be honest, I'm not 100% sure exactly what that file reports. But I do know that when it got that large, I stopped being able to open new files as any non-root user. Running basic things like 'ls' gave me errors, as they were unable to open shared libraries to run. If you like, you can read the post I originally submitted on serverfault.com, when I was trying to figure this out.
