slap_sl_free() would only reclaim memory if you were freeing the last allocated block. If you wanted to free a chain of alloc'd memory you would have to free them in the exact reverse order of allocation. Calling slap_sl_free() out of order would be a no-op. This was OK most of the time because a single operation would seldom live long enough to use much memory. But for long-lived tasks (like syncrepl or syncprov) it would often run out and allocs would fallback to ch_malloc.

sl_malloc.c in HEAD has been changed to mark freed blocks no matter what order they're freed in. It still only reclaims from the last block forward, but it's more effective now.
