    Description

      Each log slot has a buffer associated with it. That buffer is grown dynamically until it is large enough to hold the consolidated records.

      We recently bumped the number of slots, which may alter how much memory log buffers consume.

      We should consider limiting how much memory the log system can use (maybe a log cache size?). Or alternatively limiting the size log buffers can grow to - there is almost certainly a limit to how much memory it makes sense to copy and consolidate into a buffer rather than just writing it directly.
