    Default [SOLVED] imapsync timeout

    I am trying to migrate mail from one Zimbra server to another, with the same version of Zimbra using imapsync. No matter if I push from the primary or pull from the secondary, I cannot get imapsync to work, because it times out due to so many messages in the inbox. There is several GB of mail that I need to push. Is there any way to increase the timeout in Zimbra so this doesn't happen?

    It works fine using accounts that don't have as much mail.

    Can you check the value of zimbraFileUploadMaxSize on the server you are trying to upload to? The default size should be 10MB which may be why you are able to upload smaller files.

    # su - zimbra
    $ zmprov gcf zimbraFileUploadMaxSize [shows the size]

    You can try setting it to higher limits, so that it handles your large sized mails.
    $ zmprov mcf zimbraFileUploadMaxSize <size in bytes>

    You will have to restart mailboxd to reflect this change
    $ zmmailboxdctl restart

    Here is the wiki page on imap sync Guide to imapsync - Zimbra :: Wiki

    The size reports is:
    zimbraFileUploadMaxSize: 51200000

    By "smaller mailboxes" I mean ones about 1GB in size, the primary mailbox in question is over 3GB right now. So 1GB mailboxes transfer fine. I'll increase that and try again though to see if it helps.

    I was able to solve this problem by upgrading imapsync. v1.350 and higher will auto-reconnect if there is a timeout.
