OpenLDAP freezes and doesn't respond
I randomly notice my OpenLDAP server freezes, and I can't udnerstand why.
I
have a few LDAP clients (ldapsearch, a legacy Java app. and
ApacheDirectoryStudio), running from different systems,
either locally
on the OpenLDAP server, or on another OpenLDAP server, or on a remote workstation, and none manages
to get an answer
from OpenLDAP. The connection is established but each client gets stuck
waiting for any result.
The last time, it occured only a few minutes after the OpenLDAP daemon was restarted, under very low load.
I use OpenLDAP 2.4.23, over Red Hat Enterprise Linux Server release 5.4
(Tikanga), Kernel version 2.6.18-164.el5, amd64 architecture over
VMWare.
I also use BDB 4.8.30, and OpenLDAP's been compiled with the following options:
./configure --prefix=/opt/openldap-2.4.23 --enable-dynamic=yes
--enable-dynlist=yes --enable-memberof=yes --enable-ppolicy=yes
--enable-accesslog=yes --enable-sssvlv=yes
I noticed only 60 to 70 established connections on port 389 (according to netstat) when the freeze occurs.
The OpenLDAP server is set in syncrepl mirror mode replication, and
the other OpenLDAP server (only used as a hot stand-by) works fine (but
doesn't receive any load)
In the OpenLDAP accesslog, I usually see the client requests, but no lines for the responses.
Also, I noticed sometimes the "deferring operation: binding" message :
Jul 12 10:20:05 dev-ldap1 slapd[28525]: connection_input: conn=3377 deferring operation: binding
Jul 12 10:20:07 dev-ldap1 slapd[28525]: conn=3378 fd=66 ACCEPT from IP=......:3823 (IP=0.0.0.0:389)
I don't know if this message is linked or not to the main problem so I'd like to know if this message is harmless or not.
The stack of the slapd process is as follows when the freeze occurs:
