Thanks for the explanation.
So now that I know that my mailboxes.db can get corrupted what can I
do to
get away from long downtimes?
edit your cyrus.conf and change the following option
EVENTS {
# this is required
checkpoint cmd="ctl_cyrusdb -c" period=30
}
this is how

One thing I would like to know is instead of synchronising everything
can I:
1- delete mailboxe.db on mupdate.
2- do "ctl_mboxlist -d -f /var/imap/mailboxes.db >
mailbox_backend1.txt"
on both backends
3- Then on the mupdate import mailbox via:

I had many corruption problems with fedora , turns out there seems to be
a bug in mmap. RHEL 4 might have the same mmap bug.
can you check your logs and see if you find any IOERROR stating that the
mailbox file couldn't be mapped ?

Greeting, folks,
I have a Murder with two backends. We have experienced what we
believe to be skiplist corruption on the mupdate master server. More
precisely, the log show a few instance of such an error :

I use saslauthd for authentication which then uses pam. Is there a way

nice nice, I'll commence testing tonight.
on a side note, regarding that old mmap problem.. Im still testing it.
Im pretty sure its some bug in fedora's mmap.

also repeating the same process on one of the backends works
perfectly. It seems to be master related only.
do_undump in ctl_mboxlist.c have this:

making the mailboxes always type 0 , never type remote
