:When under heavy load (Opengrok indexing, Hammer daily cleanup and bulk build
:running at the same time), its swap filled entirely
:This kernel message was logged on the console:
:  swap_pager_getswapspace: failed

    Ok, I believe I have fixed the problem.  fork() was causing a
    vm_object leak where old vm_object's were not being properly terminated,
    leaving vm_page's intact and slowly causing swap to fill up.  pkgbox64
    is now running a new kernel.
