>Description:
On both 2.0_BETA and -current, pagedaemon will consume unreasonable
amounts of CPU when doing anything "serious" (i.e., spawning a vi
process, compiling anything from pkgsrc, and so forth). This results
in system stalls (on machines with large amounts of memory) and
spontaneous reboots (when memory is exhausted).
>How-To-Repeat:
Install NetBSD/amd64. Start top. Start a lengthy compile. Watch
the pagedaemon process jump up to the top of the process list; the
machine should start freezing shortly thereafter.
>Fix:
Not sure. Something clearly isn't right ...
