Also, this script just performs sync searches, what do you use to generate the writes?

you mean the write which kills the server? It just one simple mod of an object which I made in Apache Directory Studio.

I'm unable to reproduce this crash. I have your slapd.conf and test data, I have run 80-some instances of your script as you've described.

I ran 80 instances of each of the three script, where each script replicates one database, so 240 instances of the script in total.

OK. After starting 240 instances and performing the modify, I saw a SEGV due to syncprov. I've patched this in git master, please test. It runs OK for me now.

...

While the initial sync search is running I perform a modify of the base entry of the subordinate database. Everything continues to run. I've also waited for all of the initial refresh traffic to finish first, and then perform the modify, and still no crash.

To be more clear - do you perform your modify while the sync searches are still refreshing, or after all of the refreshes have completed?

IIRC it does not make any difference, but I definitly crashed the server while at least one database still replicated.

...

Do you run the clients on the same host as slapd, or on a remote machine?

I had slapd one one machine and the script on another one.
