Hi Shannon,
I suspect that the excessive temperature differences are due to
the bad sensors at M1 Edge 180 Front and M1 Edge 180 Back, see
http://sdsshost.apo.nmsu.edu/tpm/m1.html. In the archives I also
noted several spikes in the tpm_TM_M1_Denv (M1 - ambient) channel
although these were at 8/16 01:30Z and 8/16 13:15Z
TPM [Channel Access] communications errors are usually a symptom of
networking issues, was there anything significant going on?
