Interesting questions. I googled abit. I came across the patch code for 2.4 at http://linux.bkbits.net:[EMAIL PROTECTED]?[EMAIL PROTECTED]. If you look for bad_nofile, that is the a goto label for the printk("swap_free: Trying to free nonexistent swap-page\n"); code you are seeing. I am speculating wildly here with a little bit of experience. LEAF runs on RAM. Perhaps bad ram is being used where the swapfile is. The messages comes and goes because of load demanding more swap. Hence, the message every so often. The message may come during _swap_free() function call as the load is reduced on the LEAF system. You could try http://www.memtest86.com/. I used this on two different systems at a site. One had a bad piece of memory while the other had a bad CPU/motherboard--I think test 10 or 11. I put in a new motherboard and the existing memory worked ok. I am wondering if this site was hit by a surge at some point. People have given feedback on slashdot that the tool works great to verify overclocked systems. ;-) Anyhow you might give memtest a shot and see if that answer the question.
