Looks like I've found a fix (for my case). I just commented this row in .powconfig:
#export POW_TIMEOUT=999999999
When this row is uncommented then server fails to start. I'm not sure why exactly this happens but with commented row server works fine. I suggest you to try default config. Now my log looks like this:
