I don't have a second system to ssh in with but if I did, that's what I'd do as well, or try at least. Recently, I only run into trouble when a tab on Firefox goes memory hungry. Most of the time it grows slowly and I'm able to catch it. I just close Firefox or just kill that one process, which kills Tree Style Tab add-on. Once it consumes my memory and most of my swap, it gets pretty unresponsive. o_O I think I did a thread on this a while back. I'm not sure which to blame, the add-on or Firefox or even both. It's rare that I have a hard lock up that is the kernel itself. Usually I can get something to work given enough time. Still, given the amount of data I have stored here, some irreplaceable, options are nice. Good clean options are really nice. Dale :-) :-)
