    Default zimbra 7 sporadic ldap timeout

    Hello, please advise me in problem.

    Release 7.2.1_GA_2790.RHEL5_64_20120815212042 CentOS5_64 FOSS edition.

    Average instantaneous load: 300 zwc clients, 100 pop3/imap clients

    I use ZWC for email access and sometimes it hangs (2-3 times at day). Then I check zimbra maillog and see problem looks like this:

    Code:
    Jun  2 07:30:40 mailhost postfix/proxymap[19694]: warning: dict_ldap_lookup: Search error -5: Timed out
    Jun  2 07:30:40 mailhost postfix/trivial-rewrite[21065]: fatal: proxy:ldap:/opt/zimbra/conf/ldap-vad.cf(0,lock|fold_fix): table lookup problem
    And after that 15-30 seconds system unhangs and continue sending mail to users.

    I'm not sure that ldap timeout due to the increased load on the server. And we had commercial ssl certificates on the server that are not expired.

    What does this error mean ?

    Thanks.

    Default

    This means that slapd couldn't respond to the lookup request.

    Personally, I would advise you to look at migrating to ZCS8 (you will have to change OSes as part of that).
