 By default, the engine allows a total of 128 chunks `up` in memory in total, considering all chunks. This value is controlled by the service property `storage.max_chunks_up`. The active chunks that are `up` are ready for delivery and are still receiving records. Any other remaining chunk is in a `down` state, which means that it's only in the filesystem and won't be `up` in memory unless it's ready to be delivered. Chunks are never much larger than 2 MB, so with the default `storage.max_chunks_up` value of 128, each input is limited to roughly 256 MB of memory.
 
-If the input plugin has enabled `storage.type` as `filesystem`, when reaching the `storage.max_chunks_up` threshold, instead of the plugin being paused, all new data will go to chunks that are `down` in the filesystem. This lets you control memory usage by the service and also provides a guarantee that the service won't lose any data. By default, the enforcement of the `storage.max_chunks_up` limit is best-effort. Fluent Bit can only append new data to chunks that are `up`. When the limit is reached chunks will be temporarily brought `up` in memory to ingest new data, and then put to a `down` state afterwards. In general, Fluent Bit works to keep the total number of `up` chunks at or below `storage.max_chunks_up`.

 If `storage.pause_on_chunks_overlimit` is enabled (default is off), the input plugin pauses upon exceeding `storage.max_chunks_up`. With this option, `storage.max_chunks_up` becomes a hard limit for the input. When the input is paused, records won't be ingested until the plugin resumes. For some inputs, such as TCP and tail, pausing the input will almost certainly lead to log loss. For the tail input, Fluent Bit can save its current offset in the current file it's reading, and pick back up when the input is resumed.
