In both case, I think the lack of relevant information is caused by the
multithreading nature of slapd, I don't know how to access the exact
thread where the problem occurs.
I finally found how to get a better stack trace, it seems to be a locking
issue with bdb:

Do you have all the BDB 4.6 patches applied?
