The purpose is supposed to be that, over the course of the connections for
which the allocator is used, you reach a steady state where n-bytes are
the most needed at one time. Unlike the connection pool, the
c->bucket_alloc reuses memory as buckets get freed.
Bottom line: the size of c->bucket_alloc will be based on the max number
of buckets and bucket buffers you've had allocated at one time. The
answer is almost certainly that apr_bucket_destroy() is not being called
on some bucket that you're actually finished with. This could be a
symptom of discarding a brigade that still has buckets in it (since
apr_brigade_destroy() will destroy all the buckets that are in the brigade
at the time of the brigade's destruction), which is, I believe, what you
guys have said is happening in this case.
