Hi all,
In three production environment with different zimbra open source editions (8.0.4, 8.0.5 and 7.2.5) we set a live_sync following this wiki

Server Live sync - Zimbra :: Wiki

all is up and running but in all the three slave we found some logs like

2013-12-11 00:57:43,953 ERROR [RedoPlayer-37] [] redolog - Unable to execute redo op: txn 1386688703.520825 [CreateMessage] ver=1.42, tstamp=1386719095510, change=4500, mailbox=13637, id=2640, rcpt=user@domain.com, rcvDate=1386719

Checking on master server

[zimbra@master ~]$ zmprov getMailboxInfo user@domain.com
mailboxId: 13637
quotaUsed: 4202067

but on slave we have

[zimbra@slave ~]$ zmprov getMailboxInfo user@domain.com
mailboxId: 15308
quotaUsed: 0

so live sync doesn't work for this account and for many others (like 10% of total)

and now.... questione time!

do you think it's possibile to change the mailbox id in slave to match the id in master zimbra? how can we eventually check for collision?

TIA
