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 ...

Except for one "localhost", one "/tmp/.s.PGSQL..." and the "543x" lookup during the postmaster start, all lookups are IP addresses with AI_NUMERICHOST set. And we have checked with tcpdump that the box really does not issue DNS lookups.
