Sometimes my gumstix DT server gives a memory error, and then stops working --
the process keeps running, but I cannot connect to it. The most recent time
this happened i had been running span and spanToDT for a little under a day. I
think for most of this period i sampled 1 sensor every 5s, and 2 every 30s.
