overlay accesslog logdb cn=accesslog logops writes extended
The original issue should be fixed now in master.
Maybe related to ITS#7239?
Maybe the fix also addresses this issue. The problem was related to the use of an uninitialized pointer in a circumstance that could not occur when logging successful operations. I note that internal operations (related to slapo-unique(5), but also to slapo-refint(5)) get logged, or at least processed. Not sure whether this is intended or not.
