to avoid memory allocation errors of Berkeley DB add to your .emerald directory a file named DB_CONFIG containing the statement mutex_set_max 100000
  echo "mutex_set_max 100000" >> ~/.emerald/DB_CONFIG
please check the blockchain height of your EMD client.
if the block height differs from the value of 5533164 blocks you must:
  • shutdown your client
  • edit your emerald.conf by adding
    connect=65.102.140.116:12127
    connect=108.61.10.90:12127
    connect=98.115.147.74:12127
    connect=82.200.205.30:12127
    connect=46.252.49.204:12127
    connect=176.50.170.49:12127
  • change temporary the peer2peer port by adding port=12129
  • remove all blk*.dat files
  • remove the peers.dat file
  • remove the database folder
  • restart your client and let resync starts
  • check your peers info to see the "Satoshi: 0.8.6.1" or "Emerald:V0.8.7.517" protocol

after sucessfull synchronisation
  • restore the peer2peer port by adding port=12127

hint - if you want to accelerate the sync you can download the blockchain snapshot / bootstrap
  • download the latest blockchain snapshot
  • unzip the file in your emerald directory (windows: %APPDATA%\Emerald)
    you will see the file bootstrap.dat
  • start emerald-qt
  • now the Emerald Wallet should import the blockchain from your local harddrive
