Short read or OOM loading DB. Unrecoverable error, aborting now

a background

When I came to work in the morning, my colleagues reported that redis on the server kept reporting errors: # Failed opening the RDB file .dump.rdb (in server root dir unknown) for saving: No such file ordirectory 1232:M 08 Aug 14:31:07.122 # Background saving error.Seeing the error that the file does not exist, I searched in the corresponding directory and found that dump.rdb exists.So what's going on with this error?According to the redis log, it is found that reading the corresponding snapshot failed, there is no good way, restart redis and try.As a result, it can't be restarted!!!

Second source of error

      服务器上重启redis后，提示如下：
