Every time that happens I've seen it's been zerofilled (due to NFS), and not yet filled with actual data. Size might be right, but it just contains NULs.

Thank you, Aki for clarifying! you mean lines like this:

ICAgICAgICAgICAgICAgICAgCiAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAg ICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAgICAg

Hi I had the same problem

fstab: Ip:/vmail /vmail nfs rw,sec=sys,noexec,noatime,tcp,soft,rsize=32768,wsize=32768,intr,nordirplus,nfsvers=3,actimeo=120

/vmail on /vmail type nfs (rw,noexec,noatime,vers=3,rsize=65536,wsize=65536,namlen=255,acregmin=120,acregmax=120,acdirmin=120,acdirmax=120,hard,nocto,nordirplus,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=xxx.xxx.xxx.xxx,mountvers=3,mountport=635,mountproto=tcp,local_lock=none,addr=xxx.xxx.xxx.xxx)

In debian9 and debian10 an ubuntu... And I solve workaraund downgrade a kernel for all node to ... 3.x in any 4.x and 5.x I get broken file

Linux dovecot16 Debian 3.x.68-2 (kernel-care) I use netup - I don't administer it and I don't have access and only downgrade kernel solve problem
