Hi Paul, I've tried to reproduce the issue you're seeing, setting up deltasync replication and trying to send various combinations of modifies to the master. However, none of that has crashed either the server receiving the modification, nor the other servers it replicated to. No change either when the second server has to replicate directly off the accesslog database without the benefit of syncprov's sessionlog.

Is that something that you can replicate reliably? Would you be able to share the configuration (especially overlays)?

Based on the traces I've taken while testing, I haven't seen anything suspicious that the perl library would generate, but if you have the packets or slapd ber dumps, they might help confirm this for your case as well.
