我有一个cassandra，现在在启动服务器时出现此错误：

ERROR 11:18:45 Exiting due to error while processing commit log during initialization.
org.apache.cassandra.db.commitlog.CommitLogReadHandler$CommitLogReadException: Unexpected error deserializing mutation; saved to /tmp/mutation4787806670239768067dat.  This may be caused by replaying a mutation against a table with the same name but incompatible schema.  Exception follows: org.apache.cassandra.serializers.MarshalException: A local deletion time should not be negative

如果我删除了所有commitlog和保存的缓存文件，服务器就会启动，但是第二天当我重新启动cassandra时，错误再次发生。
怎么了？如何让Cassandra再次稳定？
我使用的是Cassandra3.9，但我试图升级到3.11，但没有任何改变。
