Hello,

Does anybody know how those "CRC check failed" errors can occur?

Apparently the data has been corrupted, what would be the most likely
scenario for this to happen?

java.io.IOException: CRC check failed
at
org.apache.zookeeper.server.persistence.FileTxnLog$FileTxnIterator.next(FileTxnLog.java:612)

org.apache.zookeeper.server.ZooKeeperServerMain.main(ZooKeeperServerMain.java:52)


As a result my ZK can't be started, is it recoverable?

Thanks,
Ben
