Hello,
I have a problem with OpenLDAP/back-meta in a certain setup. It sometimes stops responding to search requests. From trying to set a breakpoint in the debugger and from the syslog messages it seems that OpenLDAP doesn't jump into back-meta any more when the situation occurs. The system usually works ok for several days or weeks before the problem occurs.
The setup it OpenLDAP 2.3.35 (with some code modifications in back-meta, but the same problem occurred with the unmodified code) which connects to another OpenLDAP/back-meta installation behind a firewall and one other directory.
Both installations are on similar Linux machines, the second OpenLDAP installation has been running without problems since I upgraded it to OpenLDAP 2.3.34 as advised in ITS#4850.
What can I do to track down the problem?
Thanks Ulf Möller

Can you share you configurations?

The slapd.conf we used with the unmodified OpenLDAP code looked like this:
include /usr/local/secardeo/cert-broker/etc/openldap/schema/core.schema
pidfile /usr/local/secardeo/cert-broker/var/run/slapd.pid argsfile /usr/local/secardeo/cert-broker/var/run/slapd.args
loglevel -1
#allow bind_v2 database meta suffix ""
uri "ldap://10.138.20.9:4389/"
lastmod off
If there is any other information that I ought to mention, please let me know.
Regards, Ulf Möller

Can you assure this is not a network or firewall problem? Otherwise I can only think of I/O problems.
