I tried recompiling the Berkeley db (6.0.20) with -D_LARGE_THREADS, no difference.
I modified the test to use THR=50 and INNER ...*4 so it looks like this: ===== # Perform a basic multi-threaded search on a single connection THR=100 THR=50 OUTER=5 INNER=`expr $TESTLOOPS * 4` 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 ======= and the tests complete. Not sure how arbitrary the THR=100 is, but the 50k transactions is maintained (50 * 5 * 50 * 4) versus (100 * 5 * 50 * 2) ==== In short, using THR=50, and doubled INNER factor test060 succeeds.
Now - dies this break the test, or just show a different issue?

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

If there's no server side errors then I suppose it's a problem in mtread. Check the testrun/mtread.out file.
