To those who are getting "Idled 1 miners"-style messages in cgminer, it might be worth checking if you're hitting the cgminer overtemperature cutoff. I don't know how it is where you live, but where I am, it has been getting warmer. As a result, sometimes my Bitburners would hit the default cutoff of 60 degrees and then stop. The overtemperature cutoff is especially suspect if your miners stop once a day (since ambient temperature has a strong daily fluctuation).

The relevant cgminer option is "--avalon-cutoff" eg. "--avalon-cutoff 65" to raise it to 65 degrees. If ambient temperatures are increasing, I would also overclock a bit less, since higher temperatures seem to correlate with higher HW errors.
