   @codelipenghui thank you for reporting this. 
   
   I think there are two problems behind this issue.
   
   1) why the disk usage keeps growing?
   2) why the four entries are not available?
   
   I think the disk usage kept growing because replication worker keeps trying to replicate fragments but fail at the last 4 entries. when replication worker keeps doing that, it is writing entries again and again. so the disk usage is going up. this can be resolved when we fix #1066
   
   for the second problem, it is an interesting problem. my guess is it is related to ledger metadata update during closing. but I have to take a deeper look before coming to any conclusions.
