Indeed.

Also, you can make slapd dump core next time this happens so it's
possible to get some debug info if this happens again:
    ulimit -c unlimited
    cd <directory with room for core dumps and write access for slapd user>
    (slapd .... -d0 &) </dev/null >/dev/null 2>&1
or use some other -d<some other value> and log to a file.  The -d
ensures slapd does not detach and does not do 'cd /' - which would leave
the core dump in the root directory, where you likely do not want it.

Preferably use a slapd installed without stripping debugging symbols,
i.e.  install with
    ./configure
    make
    make install STRIP=""
