Subject: Corrupted dbox file around offset= EOF reading msg header 


Hello Dovecoters,


I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4

When I backup mdboxes (using SIS) using this command

doveadm -Dv -o plugin/quota= sync -1f -u user1 at


mails get backedup but all m files are not copied. Last file copied is m.4


If I run the command again I get below error

I tried with doveadm backup command as well (many times).


Error: Corrupted dbox file / mailbackup/user1/storage/m.4 (around
offset=3732536): EOF reading msg header (got 0/30 bytes)


Result is all mails are not backedup. Destination is a folder on a NAS with
NFS mapped to the server.
