Hello,
This doesn't seem to be arm64 related since the same occurs on ppc64el.
I've been reproducing this failure consistently by running the autopkgtest
suite on a stressed host.
I think that the failure appears under similar high-load circumstances on
the debian ci host.
dovecot-lda communicates with dovecot through the socket at
/var/run/dovecot/auth-userdb but on a stressed host
it's possible for dovecot-lda to call connect() before listen() is called
on this socket by dovecot.
By applying the suggested patch, the failure has been vanished since
dovecot-lda is called only after the socket becomes ready.
Regards,
Mpampis
