Command cbtransfer and cbbackup is not getting on 100%

Hi,
I’m trying to run a cbbackup and it doesn’t get on 100% but shows done. Even with this issue, I executed the restore command on another bucket and it brings me the same number of documents that was on the source, which gives me the impression that it worked.
I’m using Couchbase Server 6.0 and I’m with the same problem using cbtransfer, it doesn’t shows 100% but the number of documents transfered is the same then the source.

Can anyone confirm me if the commands was executed successfully even without the message 100%? And why it happens sometimes?

w0 pump (http://xxx.xxx.xxx.xxx:8091(bucket-name@xxx.xxx.xxx.xxx:8091)->/scripts/testbkp(bucket-name@xxx.xxx.xxx.xxx:8091)) done.
