I don't know what Frank is referring to, there is no bug in the checkpointing
code that I'm aware of. Nothing relevant to the checkpoint feature was
changed between 2.1.12 and 2.1.13. (Nothing there has changed in quite a
while, really.)

That's the right idea.

2.1.13 fixes a fair number of bugs. Nothing related to this though.

You didn't say anything about what platform you're running on, how many
threads slapd has configured, etc. As such, there's not enough information
here to make a meaningful comment about memory usage.
