Applies to:Oracle Directory Server Enterprise Edition - Version 22.214.171.124.0 and later
Information in this document applies to any platform.
ODSEE 126.96.36.199.0 on Red Hat Enterprise Linux 5 x86-64
The ns-slapd process crashes randomly.
There are two servers in MMR. They are behind a Load Balancer which is used for the clients.
There is an application (Critical Path Meta-Directory Server) that is used by LDAP server as repository. This application goes directly to one ldap master without passing through the Load Balancer.
Every time the server crashes we lose the Metadirectory service and it's necessary to restart the server.
From 2 dirtracer outputs, gathered with option 0-Server Down, we can see following trace under pkgapp.backtraceXXX file:
Recently enabled the index filter analyzer in these LDAP servers and there are Metadirectory base=one searches.
