Bitcoinj stuck after chain split

2017-05-23 Thread BitcoinUser 


I am using LevelDBFullPrunedBlockStore as a BlockChain. once in every 2-3 
chainsplit in the network my bitcoinJ node stops to download new block. The 
scenario is always the same

1)My node get block on height x that network will mark as orphaned later
2)My node gets block x+1 (from mainchain) and says that block x (orphaned 
by the network later) will be orphaned 
3)My node get the mainchain block on height x and says that "could not 
verify block"

Later peers are sending me single transactions, but I am unable to download 
any more blocks, there is no logs about the new block at all. I did not 
change anything in the code that is responsible for block persistence. When 
I restart the application it does not download any new block as well.

Here is log form Saturday where it happend:
