    Default ZimbraLDAP could not start completely

    Hi,

    Our customer reported a problem with starting LDAP.

    They restarted LDAP via zmcontrol stop/start in order to backup
    BDB on LDAP.
    1. zmcontrol stop
    2. cp -r /opt/zimbra/open-ldap /opt/zimbra/open-ldap.bak20100902
    3. zmcontrol start

    It seemed ZimbraLDAP started from logs, however our customer
    said the server was unresponsive when executing ldap search.

    They also said that when the server was unresponsive, there were
    around 100 connections whose status were "ESTABLISHED" with store servers.

    Could you figure out the problem?
    I think the connections from store server could exclude the ldapsearch,
    but I'm not sure why so many connections were established. They
    didn't use ldap connection pool.


    Here is the zimbra.log:

    Default

    You need to give some details about the configuration of your server(s), single server, multi-server or what? What's the status of the Zimbra services? What does the following show:

    Code:
    zmcontrol status
    Is the ldap search being done on the Zimbra server or from a remote client? Has this worked in the past? Which version of Zimbra is this (is it the one in your signature)?
    Regards

    Sorry, we are running multi-server, 10-15 stores, and separate LDAP master/replicas, proxies and MTAs.

    On the LDAP master server, the result of zmcontrol status was:
    ldap : running
    stats: running
    Ldap search being done on the Zimbra server(ldap master),
    and that worked in the past.

    And the Zibmra version is :
    Release 5.0.16_GA_2921.RHEL5_64_20090429021719 RHEL5_64 NETWORK edition
    Could it be helpful?
