Ah, SIGPROF. This is a common side-effect of overflows in the
per-process kernel stack. Shortly after 4.4-RELEASE the size of
the per-process kernel stack was increased due to this problem.

If you cvsup to 4-STABLE, or alternatively change the definition
of "UPAGES" in /usr/src/sys/i386/include/param.h from 2 to 3
and rebuild your kernel, then the problem should go away.
