Yes, I have set up rootdn because pcache overlay wanted it. I will set also some rootpw to see if this makes difference.

mmmh, sounds like a red herring, sorry for the noise.

Hello, The bug seems to be in the new code in pcache overlay handling cache refreshes. When I switched configuration with only TTL/negTTL (without TTR) the crashes have disappeared from both scenarios I have used:

1. One process with back-sql + pcache (crashed with segmentation failt when using TTR)

2. Two processes, first with back-sql, second with back-ldap + pcache, that communicate over unix domain socket (crashed on assertion in entry_clean when using TTR)

So the bug is not fixed but is located in pcache > consistency_check > refresh_query
