As per <http://wiki2.dovecot.org/Migration/Dsync>, I'm running the
following command on a local dovecot server to replicate email for a
single user from a remote IMAP server:
doveadm -D \
-o imapc_host=remote.imap.server \
-o imapc_user=gcr \
-o imapc_password=XXXXXXXX \
-o imapc_list_prefix=IMAP \
-o imapc_features="rfc822.size fetch-headers" \
-o mail_prefetch_count=20 \
-o mail_fsync=never \
backup -R -u gcr imapc:
This runs fine for a while and successfully copies quite a lot of mail,
but always aborts before completion with the following error:
dsync(gcr): Panic: file mail-transaction-log.c: line 271
(mail_transaction_log_rotate): assertion failed: (file->locked)
The exit code is 262. Does anyone know why this might happen or how to
fix it?
