The /frames file system was 100% full, which means no new frames
were being written by the daq.

I have written a primitive script to just delete the oldest full frame
and second trend frame directories if /frames gets bigger than 95%.

The script runs as a cron job, as user controls on seiteststand


# Every hour run script to keep /frames from filling
# check /tmp/daq_wiper.log for its logs
