[RHDS 8.1] ns-slapd segfault at 0000000000000000 during replication agreement removal or creation

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 5.5
  • RHDS 8.1 - Multi Master

Issue

  • When trying to delete a replication agreement and create a new one, console did not confirmed the operation and stopped to respond (clicking in different buttons does not produce any action or confirmation).

In /var/log/messages the following error was presented:

Sep 23 11:34:16 example kernel: ns-slapd[11780]: segfault at 0000000000000000 rip 00002ba262dd2de0 rsp 000000004ef249f0 error 4
  • "ps" command showed that ns-slapd was not running anymore. So, probably it died after the segfault error. Because of it the administration console did not respond properly to the executed actions.

Resolution

This is a know bug in RHDS 8.1 and it was fixed and backported in version 8.2 (redhat-ds-base-8.2.1-1.el5dsrv).

Update this package for the latest version or at least 8.2.1-1, restart all RHDS components and this problem will be solved.

Root Cause

It was a bug in RHDS 8.1.

Diagnostic Steps

Check if /var/log/messages contains ns-slapd segfault while the administration console did not respond properly anymore.
