-G Force re-parsing of the underlying message (checks GUID
correctness). Reconstruct with -G should fix all possible individual
message issues, including corrupted data files.

Since I couldn't get a successful reconstruct on this account, I
deleted it and recreated it from my master host. However, I'm still
unable to get a successful reconstruct with "failed to read index
header" for every subfolder and "fatal error: Internal error:
assertion failed: imap/mailbox.c: 2847: record->size"
Any ideas on how to correct this so I can see if I can then get past
the replication error?
Thanks!

I then restart the replication against the log-run file and it again

Looks like you have a corrupted mailboxes database - if you run a
reconstruct at each end then it should be fine. Replication won't
bail for an actually-doesn't-exist mailbox, but it can't fix broken
mailboxes, that's what reconstruct is for.

Hi list, I'm running cyrus replication on cyrus 2.5.10. It seems
whenever a folder is encountered in log-run that doesn't exist on the
client and/or the server, the replication process logs "Error in
do_sync(): bailing out! Bad protocol". Sometimes, it dies
completely,
other times it restarts at the beginning of the log-run file. But
when
it re-encounters the folder in question, the same failure occurs
and the
problem continuously loops until some manual action is taken. I
have a
checker script that attempts to restart a stopped sync but I haven't
tried to code it to get past these types of folder errors. In the
meantime, replication effectively stops and the replication log
continuously builds in size. You might imagine my horror at
discovering
yesterday that replication of my production server with 1200 accounts
had been failing for over 7 weeks unnoticed, generating 9.5 million
lines in the replication log files. I had gotten out of the habit of
daily monitoring of replication as it had been running fine and I
eventually moved on to other things. I'm trying to get
replication to
run through the enormous backlog but am running into more similar
folder
issues that cause the process to fail, I make manual fixes, and start
the process again. In my experience with this, reconstruction of the
affected folders on the master host and copy host has no effect.
Can this otherwise excellent feature be made more robust to work past
these folder issues?
Here are a couple of examples I've observed thus far of how the
process
is failing for me.
--------------
In this example, the subfolder "Fly America Foreign Travel" no longer
existed on the master host but did exist on the copy host. To
resolve
this, I had to manually delete that folder from the copy host.

In this example, the subfolder "Sohn" did not exist on the master
host
nor on the copy host. To resolve, I had to edit log-run and
completely
remove all entries for this "Sohn" subfolder.

Often, errors are logged without "bailing out!" and replication
continues to run:
