Hi,

I have setted up two multimasters in mirror mode.

After launching in debug mode with -d 16384 once I stop the slapd ( by CTRL+c )
I obtain a bus error.

below the analysis of the core:

[New Thread 1 (LWP 1)]
Loaded symbols for /usr/lib/64//libthread.so.1

warning: Can't read pathname for load map: I/O error.

Core was generated by `libexec/slapd -f etc/openldap/slapd.conf -h ldap://:379
-d 16384'.

Hello,

Thanks for the report, and I apologize for the delay in responding.  I 
would note that 2.4.21 (at this point) is ancient, and there have been 
numerous fixes to Multimaster replication since that time.  I would note in 
the future, if you choose to file a report, your exact configurations would 
also need to be supplied for a report such as this one.  There was nothing 
particularly actionable based on this report.

This ITS will be closed. If you can reproduce this issue with a current 
build of OpenLDAP, please file a new issue.

Regards,
Quanah
