    Default [SOLVED] Zimbra stopped working suddenly, need advice

    The server has been running fine for about a year and yesterday it abrubptly stopped working, the admin page and login page just time out. I'm trying to refresh my memory and get caught up on the documentation as well as searching the forums but no luck yet.

    Here are the results of what I've done so far -

    Code:
    su zimbra
    cd /opt/zimbra/bin
    
    zmcontrol status 
    Unable to determine enabled services from ldap.

    Looks like someone else is having the same / similar issue (see Zimbra not running). Not sure, but I'm thinking it could be an issue with self-signed certificates. Search the Zimbra Wiki for more info.

    You should look in the log files for any errors but, as soxfan suggested, I'd also guess it's the certificates from your highlighted comment.

    Used these instructions to fix, thanks for the replies:

    Code:
    Single-Node Self-Signed Certificate
    
    1. Begin by generating a new Certificate Authority (CA).
    
    zmcertmgr createca -new
    
    2. Then generate a certificate signed by the CA that expires in 365 days.
    
    zmcertmgr createcrt -new -days 365
    
    3. Next deploy the certificate.
    
    zmcertmgr deploycrt self
    
    4. Next deploy the CA.
    
    zmcertmgr deployca
    
    5. To finish, verify the certificate was deployed to all the services.
    
    zmcertmgr viewdeployedcrt

    Also wanted to add a comment about this. Seems like this would be a fairly common problem. I'm a little confused about why this would cause the entire server to fail and then consequently not start up again. The error message you get from zmcontrol and the main logs I check say nothing about a certificate expiring.

    Seems like logging could be improved in regards to this, unless I'm missing something.
