I was observing it on FreeBSD 4.11 running nagios 1.2. Xach, one of
the dev guys here spotted, and appears to have corrected the issue, at
least on FreeBSD.

Xach:
It turns out our local modifications to the service_message structure
pushed it over 512 bytes, making its write() over the pipe in
write_svc_message non-atomic. read_svc_message was then reading only a
partial message, and the zeroed-out fields triggered the "did not exit
properly!" errors.
I posted (via gmane) to the nagios-devel list with the details and a
patch.
