I am using ZCO 5.0.22 and used to open 6 other user's mailbox without any issue and/or error. Although for any closing and re-added a mailbox, it will select a higher number for the zdb (eg. Zimbra2.zdb, Zimbra3.zdb etc).
However, this morning, when I try to add another user's mailbox, which has been assigned a 2 digit number (ie. Zimbra10.zdb). Since then, I've been keep on getting unknown sync error in Zimbra Send/Recive Progress screen, and nothing is being sync on it.
I've tried to closing some other mailbox which used to work and add it back, of course it got a higher number (Zimbra11.zdb), and now this mailbox also got the same error. Have tried a few mailbox which ended up on the same situation and was the same.
The one I didn't closed still works. Any once I closed all the one have issue, which all has number higher than 9, there is no more sync error. Once added it back (which got another higher number), error comes back.
As for that user's mailbox, I've also added to my other workstation which works completely fine. However, this workstation only have single digit zdb number. Hence, seems like it's not the mailbox account issue.
I've also tried to repair ZCO, and the result is the same. Thus, I am wondering if there is any limitation of the zdb numbering which causes issue? If so, how can I set it back to use a lower number? I tried to remove all the zdb file from Zimbra3.zdb and up, but when open the user's mailbox, it still keep on assigning higher number. Seems like it's caching the assigned number somewhere.
Anyone has experience on this, and any advice?
