    In any case, the machine can freeze once you
    start using the swap area. So, I wouldn't say it is important
    to choose a big or a small swap partition.

    I have not seen any of the alleged problems with swapping. I
    certainly haven't seen freezing or crashing due to swapping. I have
    seen one problem on one machine that may be attributable to a bug in
    the VM code (or may reflect marginal hardware). Let's get together at
    IWP9 and figure out if the alleged swap bugs are real or urban myth.

    I have experienced freezing due to what I assume is swap on two
    machines. Both had low memory, and would lock up completely when I was
    compiling a kernel and reached a certain swap usage (perhaps 30%). I
    didn't test the problem with anything else, so it could possibly be a
    problem in the kernel compilation procedure (I personally doubt it),
    but one machine had 32 MB of RAM and the other had 64, and both would
    only lock up once they had hit a certain swap usage.

    This just sounds like thrashing. Was the disk active when the machine
    was `frozen'?


  5. Re: [9fans] termrc changes

    i have seen the same on a machine with not much memory
    (actually not much recognized memory, now fixed).
    certainly not thrashing as there was no disk activity.

    i'm now in Madrid and have had my jet-lag busting sleep.

    Yes, Bruce seems to have had the same problem as I did. I can't
    recall--does this make the mouse stop or not.

    I wasn't using a mouse on the console but certainly the
    drawterm wouldn't do anything sensible.
