Re: NAMD node freeze

Thanks for the insight into your experiences with a diskless cluster. I
don't think cooling or voltages are a problem as I have lm_sensors
installed and everything has been well within range. If no one has any
other suggestions, I think I will first try installing a Intel
pro/1000MT (which is what I have in all of the other nodes). If that
doesn't work, I will be forced to install a hard drive. If that
doesn't work, than I am really stumped, because this will make all of
the machines identical, and it is only the two diskless ones that are
giving me fits.
Thanks again,
