I'm suspecting here that we simply leaked a refcount on every darn pagecache page in the machine. Note how mapped memory has shrunk down to less than a megabyte and everything which can be swapped out has been swapped out. If so, then oom-killing everything in the world is pretty inevitable. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
