I found what appears to have been the problem.
A canonical name from a DNS, for IP address 67.89.155.246, was listed in the cache file as "pacificdesignspecialist-pacificdesignspecialist-psr897661.z155-89-67.customer.al" plus three non-alphameric characters at the end ( and ή). Analog did not report this as a corrupted line in the DNS cache, but QDNS quit reading the cache file at that point, reported "551 DNS Entries loaded ..." and lost every resolved IP address after that ~ cutting the file to one-seventh of its actual size. I found the entry at about line 551, deleted the three characters from my backup file, saved it as the cache file, and QDNS handled it properly. So did Analog.
Considerably faster.
But it ate my cache file at least once when I didn't have a backup. Rebuilding it will probably go faster now that I'm aware of the problem.
