I'm seeing random failures with test050 and current HEAD. this time I saved the testrun dirs. There seem to be two different kind of failures: - one kind can simply be related to uncomplete synch between the different instances of slapd (database differs); - the other one worries me more:
[luca@luca-nb tests]$ ./run -b hdb test050 Cleaning up test run directory leftover from previous run.

Seems like server3 never received the config entries for dc=example,dc=com. I haven't been able to reproduce this issue. I suppose this indicates a race condition somewhere in the initial refresh. What kind of system are you testing on? Can you try inserting a "sleep 3" at around line 277 of test050, right before "Adding schema and databases"...

I'm testing on FC8 on my laptop (pentium M 1.8GHz, 2GB RAM). db-4.6.21, cyrus-sasl-2.1.22, openssl-0.9.8g all from tarballs. I too can hardly reproduce it: say, once in 20 or so runs. I've been able to reproduce again even with the suggested delay. Attached are the directories resulting from two failed runs. testrun.f1 shows different databases at the end of test050 testrun.f2 shows the results of this run: [luca@luca-nb tests]$ ./run -b hdb test050 Cleaning up test run directory leftover from previous run.

That worked for me. I'm just building HEAD so I can test soem changes to test006-acls
