The above had nothing to do with your problem.  Your problem is related
to the fact that you intermixed overlay and database configuration
statements, so the idletimeout statement after the accesslog overlay
instantiation was causing invalid memory write (beyond the private data
of the accesslog overlay instead of in the private data of the bdb
database) resulting in heap corruption.

Maybe it hasn't been stressed enough, but the order of directives is:

- global

[- global overlay
[- global overlay
[...]
]]

[- database

[- overlay
[- overlay
[...]
]]

[- database

[- overlay
[- overlay
[...]
]]]]

and each overlay's directives have to appear before any other overlay's.

I'll see if sanity checks may be added to avoid your issue.
