Hmm, that's really bizarre.  It seems like the only satisfactory
explanation for that would involve some external condition that varies
over time.  I'm wondering about DNS lookup results in particular.
What values are you asking getaddrinfo to look up, and might those
involve consulting DNS?  If so, try to correlate the crash probability
with changes in your DNS zone contents ...
