can you take a system call trace - perhaps the gethostbyname_r call was
unable to allocate a file descriptor on which to issue the DNS request.
perhaps the failure mode was leaving fd's behind. you could also see
about using ulimit/setrlimit to up the maximum number of FD's per
process, but if there is indeed an FD leak that only delays the
inevitable.
