As to your question, Spiro ... I wonder about a couple of things.
1. Is the first use of the swap partition associated with the failures? This is tough to spot from the logs; the only way I've found to watch for it is to open an ssh session from a LAN workstation to the router and run "top" ... so I can see the router's recent state (regarding swap, among other things) just before it failed, after the failure happens.
2. How much memory do you have, and how big a swap partition? What happens if you disable swap (since the system works fine in a no-HD configuration, you presumably don't *need* the swap partition)?
3. How big is the power supply? One difference between the two setups is that a system with a hard disk draws more power than a diskless one, and if the system is failing under heavy CPU load (that's what it sounds like from your description), it might be a power problem. (It's happened to me with low-end workstations, though not with routers.)
4. In re-reading your message, I realize I assumed, perhaps rashly, that the HD and no-HD systems are identical in all other respects (I first assumed they were the same system, with and without the HD, but I now see you didn't say that at all). Are there *any* other differences between the two test systems? After you do the check in item 1, do you see any pattern about how much RAM is used just before the failure (might the HD system have a bad spot high in real memory)?

I've been using a hard drive with LRP the past few weeks, following the
LRPHardDiskHOWTO guide found at Charles Steinkuehler's website. I've had
success with getting it up and running, but it seems to exhibit a general
'flakyness'. For example, when performing a PPTP-over-PPP reconnect test (cut
the connection and have it reconnect over and over), after a some time the box
will just crash hard ( unable to do or type anything or see anything on the
screen) ,with no error messages in the logs or anything. The same tests work
just fine on a normal no-HD LRP box with the same software. I was wondering if
people using a hard drive with LRP have had any such problems.
I'm using a 2.2.19 kernel with a 40GB IDE drive, with 3 partitions: a 100MB
FAT16 boot partition, a swap partition, and root on the 3rd partition using the
rest of the disk. I've used ext2 and reiserfs for the root partition with more
or less the same results. I don't think the drive size should be an issue. I
don't see any error messages on bootup or elsewhere.
One thing I've noticed is that the swap partition is always assigned a
priority of -1 (regardless of the value in /etc/fstab). Could this or the swap
size be an issue?
Any help/guesses would be greatly appreciated. Thanks.
