Dev, our wallet stuck every day several times per day for last months. Every day we have to restart it in order to make it sync further. The time on our server is precisely correct and synced well. We are using version 1.2.8. Please, advise - this issue need to be fixed.
Sometimes we see something like that:
2017-05-14 08:07:45 SEVERE: Block not accepted
nxt.BlockchainProcessor$BlockOutOfOrderException: Invalid timestamp: 87026881 current time is 87026865, previous block timestamp is 87026844
