Thank you again, Quanah
Ok, well, that's bizarre. The issue with the accesslog DB still exists too though. :) I would guess that that's the database that got resized. Guess the next question is, where did they get a program that's illegally accessing the slapd database and attempting to resize it.
Maybe I got this correctly, but besides the use of mdb as backend and, maybe the accesslog overlay, my setup is quite ordinary. Speaking in accesslog, I have logpurge 00+00:10 00+00:10, which I think is a little too often. However, the problem occurs in such a way that is well time spaced. It's trully bizarre.
