Unfortunately that helper does not have much debug to figure out why its
crashing. There are a couple of bug reports open about this crashing,
but only after its been running a while in some past execution.

The current workaround seems to be erasing the cert DB it uses and
re-generating it. Any help debugging that would be very welcome.

That is a known bug on BSD. The child process fork()'d to run the helper
already has been down-privileged by Squid. On BSD systems that means the
test to see if it is still root fails - unfortunately loudly.
