running slapd under valgrind

HI!

An Æ-DIR installation with self-compiled OpenLDAP 2.4.53 on Debian (now buster) has memory leak issues on the Æ-DIR providers. The read-only consumers do not have this issue. The provider config is more complex with more overlays.

slapd is automatically restarted (by monit) when memory consumption reaches 80%. Thus monitoring clearly shows a frequent saw tooth pattern.

I'm experimenting with valgrind to track down the issue:

valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --verbose --log-file=valgrind-out.txt -- /opt/openldap-ms/libexec/slapd [...]

Does that make sense or are some other command-line options needed?

Ciao, Michael.
