错误如下：
EXCEPTION: 15dbwrapper_error
Fatal LevelDB error: Corruption: bad record length: /data/coin/btc/indexes/txindex/905342.log
bitcoin in AppInit()
之前查找这些关键字15dbwrapper_error，Fatal LevelDB error没查出什么问题，后面进去目录/data/coin/btc/indexes/txindex看了全是ldb结尾的数据文件，但是却不知道为什么出现了一个905342.log 文件，我不清楚是不是这个原因引起的，于是我先将这个文件转移到其他路径，再重启节点于是又开始重新同步了。
