Looking through my messages file, I see towards the top the following
pair of messages:

Aug  2 09:38:08 localhost epmd: epmd: epmd running - daemon = 1
Aug  2 09:38:08 localhost epmd: epmd: epmd running - daemon = 1

After that, I got lines like the following until I ran out of drive space:

Aug  2 09:38:08 localhost epmd: epmd: error in accept
