Well, it looks as though I may have been seeing strange fallout from having multiple lines allowing access from the same IP addresses in an access list. No warnings about splay trees when I used that config, though. Hmm. And it's been working for months like that. Anyway, cleaning up the access list has cured the symptoms for now.
