Too much ram: it’s possible


I’ve always said you can’t be too rich, too thin, or have too much RAM.  (I’m paraphrasing a quote from the Dutchess of Windsor.)  However, maybe you can have too much RAM.  Recent changes by Matthew Dillon have made it possible to run the kernel_map out of RAM depending on the quantity of video RAM and system RAM in use.

This isn’t a significant danger; I’m highlighting it because it’s an odd problem.  It’s easy to work around for now.  There’s a new utility, kmapinfo, to show mow much kernel memory is being used.
