    ReplyDelete
  2. another solution
    this working for me

    try this:

    1. stop zimbra ----> zmcontrol stop
    2. delete redolog directory ---> /opt/zimbra/redolog
    3. create a new redolog directory ----> mkdir /opt/zimbra/redolog
    4. change owner ---> chown -R zimbra:zimbra redolog
    5. change permissions ----> chmod 755 redolog
    6. start services ----> zmcontrol start

    Zimbra working again!
