what is this ?

Lost blocks
your wallet is re-syncing, maybe it just crash or, it is designed like that..
you should be aware that while wallet is resyncing, block is going up so fast, if pool accepted share during that resync blocks and pool has positive balance, there will be huge chance that miner will got paid huge amount, because that miner could be the only one that has share in that block,
thats why my pool has funky payment while wallet is constantly crashing
