Hello
This is my setup:
o Old server: RHEL 7 x64, dovecot 2.3.13 from dovecot RPM repo
o New Server: RHEL 9 x64, dovecot-2.3.16-15.el9.x86_64 (rhel rpm)
I am migrating several thousand mailboxes with doveadm backup, >99%
worked, but 3 of them fail:
doveadm(mbejdom)<KlUSFVAuEGnASxcAVKmH5w>: Error: read(myserver) failed:
EOF (last sent=mailbox, last recv=mailbox)
doveadm(mportcal)<rFRoEw0zEGl+XBcAVKmH5w>: Error: read(myserver) failed:
EOF (last sent=mailbox, last recv=mailbox)
doveadm(agalmun)<1l2fMZFoEWnoGhgAVKmH5w>: Error: read(myserver) failed:
EOF (last sent=mailbox, last recv=mailbox)
When I enable debug in doveadm backup this is what I get in one of them:

In the old server I get this log:

I have tried doveadm force-resync but still get the same error.
What can I do to troubleshoot what is happening? I attach doveconf -n
