I believe I have found a CCSM/POP bug in tavg.F, where it searches the string tavg_outfile_temp, looking for 'hist', to change to 'rest' (around line 1600). I had at first named my historical case Thist, so the file path included the string 'hist'. At restart time, the code erred because it could not find a restart file of the name ..../Trest/ocn/hist/...
I believe that the tavg.F coding spotted the hist in my job name and changed it to rest, rather than the intended hist farther down in the path. I since renamed the job and it ran fine.
