I really haven't the foggiest where to look :-( I don't actually believe that it's a spinlock problem; that would explain pages getting substituted for other pages, in whole or in part, but you showed at least one example where a page was just overwritten with garbage. That looks more like a memory-stomp problem (again, assuming that it's software) and so could be anywhere. Are you using any off-the-beaten-track code (contrib modules, non-btree indexes, non-mainstream data types)? That stuff is less well debugged than the mainstream ... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
