Note: tried nofiles=5000 and nofiles=10000 - no change.

I am beginning to think it could be related to this:

*Limits and Default Values*
The threads library has some implementation-dependent limits and default
values. These limits and default values can be retrieved by symbolic
constants to enhance the portability of programs:

   - The maximum number of threads per process is 512. The maximum number
   of threads can be retrieved at compilation time using the *
   PTHREAD_THREADS_MAX* symbolic constant defined in the *pthread.h* header
   file. If an application is compiled with the *-D_LARGE_THREADS* flag,
   the maximum number of threads per process is 32767.

===

Made this small change to the test:

# Perform a basic multi-threaded search on a single connection
echo Perform a basic multi-threaded search on a single connection
THR=100
OUTER=5
INNER=`expr $TESTLOOPS \* 2`
for THR in 60 62 64 65 66 67 68 69 70 80 90 100
do
echo "Testing basic mt-hot search: $THR threads ($OUTER x $INNER) loops..."
echo $SLAPDMTREAD -H $URI1 -D "$MANAGERDN" -w $PASSWD \
        -e "$MONITORDN" \
        -m $THR -L $OUTER -l $INNER
$SLAPDMTREAD -H $URI1 -D "$MANAGERDN" -w $PASSWD \
        -e "$MONITORDN" -f "(objectclass=*)" \
        -m $THR -L $OUTER -l $INNER >> $MTREADOUT 2>&1
RC=$?
if test $RC != 0 ; then
        echo "slapd-mtread failed ($RC)!"
        test $KILLSERVERS != no && kill -HUP $KILLPIDS
        exit $RC
fi
done

Got this as output:

Shall test after new build with CFLAGS=-D_LARGE_THREADS
