:the timeout to kill it off because of the interactive mode. Otherwise
:there was ~960,000 accumulated exec()'s altogether in a 5 hour period.

:As you can see, cron is the process that crashed it. Two weeks ago it
:was an eggdrop. I've not had any crashes in -CURRENT while this program
:was not running however.

:If you notice, both times it crashed on vm_map_insert.
Try bumping up PMAP_SHPGPERPROC. From LINT:
#
# Set the number of PV entries per process. Increasing this can
# stop panics related to heavy use of shared memory. However, that can
# (combined with large amounts of physical memory) cause panics at
# boot time due the kernel running out of VM space.
#
# If you're tweaking this, you might also want to increase the sysctls
# "vm.v_free_min", "vm.v_free_reserved", and "vm.v_free_target".
#
# The value below is the one more than the default.
#
options PMAP_SHPGPERPROC=201
Try bumping it up to 1000 and see if that solves your crashes. If
that doesn't work, and there's any chance of getting a kernel dump,
try getting a kernel dump. Make sure you use a debug (compiled -g)
kernel.
