Re: deferring operation ?

These directives are in my slapd.conf :

idletimeout 30
timelimit 30

Do i have to try these lower ?

Thanks for your help,

Roderick.

This is your problem:
Jul  4 13:50:03 annuaire slapd[19523]: connection_read(18): no connection!

That is why it is deferring the operation.  A quick google on that
shows some tuning of idle timeouts and possibly ulimit might be
helpful.  I would recommend that you start tracking connections and
file descriptors to get a feel of conditions surrounding your
"freeze".

Hi,

I'm facing a problem with my openldap server.
It freezes sometimes (and no longer respond to other requests) with this
message on the log file :
*Jul  4 13:50:03 annuaire slapd[19523]: connection_input: conn=7554
deferring operation: binding
*
I couldn't find anything on the archives about this problem. I tried to
reindex the database, open acl search for anonymous and turn off all
logs but it doesn't completely solve my problem (the freezes happens
less times a day but my server still doesn't talk back sometimes)*.

*Here is my config : (Bi-pro Xeon - 2 Gb RAM) RedHat EL AS 3.0 -
openldap 2.2.13 - BDB 4.2.52 and ldap is used by mail and SSO (postfix -
cyrus-imapd -saslauthd and Yale-CAS)

Here is the full log message for a request :
