Hello,
I see several topics about cbbackup hangs, but it doesn’t seems to have any solution.
In our case, we use Couchbase 3.0.1 on our server, and for backup we use “couchbase-cli” 3.1.6, and when we use “cbbackup” on a specific bucket, the backup hangs (backup work well during several months before this)
In this topic: Cbbackup is hanging, there is a reference to this ticket:
https://issues.couchbase.com/browse/MB-13386
But there is a difference, because on server we only see this line on logs:
Fri May 26 15:49:02.536534 UTC 3: (objects) DCP (Producer) eq_dcpq:cbbackup-HYFiNUkxpmvPJAGa - (vb 122) stream created with start seqno 0 and end seqno 131127804
No other message, with cbbackup tools on verbose mode:
$ ./cbbackup --single-node http://127.0.0.1:8091 /var/couchbase/backup -m full -vvv -t 1 -b objects

After a SIGINT on Couchbase server:
Fri May 26 15:49:02.536534 UTC 3: (objects) DCP (Producer) eq_dcpq:cbbackup-HYFiNUkxpmvPJAGa - (vb 122) stream created with start seqno 0 and end seqno 131127804

Do you know how to resolve this please ?
Thank you.
