The fire does not extinguish with kill-buffer and undo history grows indefinitely #3

Emacs then complains

Warning (undo): Buffer *fireplace*' undo info was 13108363 bytes long. The undo info was discarded because it exceededundo-outer-limit'.

This is normal if you executed a command that made a huge change to the buffer. In that case, to prevent similar problems in the future, set `undo-outer-limit' to a value that is large enough to cover the maximum size of normal changes you expect a single command to make, but not so large that it might exceed the maximum memory allotted to Emacs.

If you did not execute any such command, the situation is probably due to a bug and you should report it.

You can disable the popping up of this buffer by adding the entry (undo discard-info) to the user option warning-suppress-types', which is defined in thewarnings' library.

Only ''fireplace-off'' is supported for now. I will add supporting ''kill-buffer'' to the todo list. Buffer-undo should be disabled, do you have any hooks on special-mode that might have re-enabled buffer undo?
