OS bug? Race condition? Valgrind bug, since it so far will only happen under Valgrind? > Have you seen this with CONNS debug messages enabled? Full testrun dir in <http://folk.uio.no/hbf/testrun.1.tbz> from GRIND=valgrind SLAPD_DEBUG=269 ./run test050 (I've done s/exec/exec $GRIND/ on last 'exec' in servers/slapd/slapd).
