What is uniquemember.so? Is it a custom overlay?
Ciao, Michael.

So if slapd is crashing with a custom overlay loaded you should probably
ask the author of this overlay what's wrong.
Where did you get this overlay from?

Ciao, Michael.

Dear,
This overlay was developed in 2006 when our organization moved to OpenLDAP.
We just migrated existing config. & data from 2.4.xx (bdb) to 2.4.46 (lmdb).

Did you recompile the overlay for 2.4.46?
I'm also pretty sure that the API changed within the 2.4.x release
series. So you might also need some code changes therein.

See for example ITS#8435: http://www.openldap.org/its/?findid=8435
Your overlay might require changes like these:

That looks like either:
- You have a bad SIM (very unlikely)
- You have a corrupted uniquemember.so.0.0.0 shared library.
- You may have conflated OpenLDAP packages installed that have a critical
incompatibility amidst the installed binaries/libraries.
It did write a core file; there are many tutorials about exploring
a core file to help understand why the segfault occurred.

Who's responsibility do you think this is?
From what I can tell, the OpenLDAP project only supplies source code.
https://www.openldap.org/software/download/
Who installed those binaries? Where did they come from?

Dear Brian,
Sincere apologies but am literally clueless what to do next now because of
this frequent crash & impacting routine operational task. Hence, need to
get this resolved at the earliest with your (& all ) help.
This is a custom overlay build in 2006 by our ex team mate & he did the
installation on older versions. This August we did a migration from old
version to 2.4.46 & lmdb backend. Is it that we skipped some steps in this
movement..?

Ah, that's _very_ relevant information. Without knowing anything more
about your setup, that custom overlay would be the very first thing you
should look at. There's very little a mailing list can help with,
concerning a custom overlay.
Probably the best thing you can do in the immediate term is to revert to
a backup of your previous system, presuming such a thing exists, and
that the previous system is (at least) basically working. Then you need
to find someone who's able to look at the custom overlay code. It might
be worth trying to work out if you can do without the overlay.
I notice that there's an ongoing list thread 'help to get our openldap
updated and replicated'. That thread might be worth monitoring, on
general principles.
Best wishes (and good luck),
Norman

this frequent crash & impacting routine operational task. Hence, need to

This is a custom overlay build in 2006 by our ex team mate & he did the
installation on older versions. This August we did a migration from old

movement..?
I'd say yes: You should have checked that your custom module is ready for a software
upgrade. Maybe go back to the software that worked until you have another that works
also.
