[2018-01-21 16:20:42.9106] [I] [StatsRecorder] Updating hashrates for pool exp1

[oliverw]

Make sure your pool config (the element for your ethereum pool, not the whole cluster config) contains the following element and the user the pool is running under has full access to that directory:

"dagDir": "/data2/dag/eth1",

"dagDir": "c:/eth/dag",

Sorry did not work out :(

When I use "dagDir": "c:/eth/dag" there is a dag in the folder but still memory exception.
When I use "dagDir": "/eth/dag" , I even do could not find where the folder is created and still memory exception. Screenshots are below.
