Correct? If that is the case the only way around it to dump/load or checkout fresh version?

You could try it and find out.

You will not have a problem, because at revision 115 there is no
file/folder named "aux" anymore, is there?  A checkout does not get
revision 0 and then sequentially apply each subsequent revision to it.
It only gets the state of the repository at the revision you've
checked out.

>>> Drop revision I mean using svnadmin (not svn for safety) and truly delete down
from HEAD to lower revision. It is kind of what I did in a long walk by dumping -r 1:1001
and loading it back. Perhaps svnadmin trunk -r 1001 (1002 and 1003 would get truly removed).

There is some very preliminary work & discussion underway to build a
more usable means by which items can be "obliterated" from the
repository history without having to perform the current steps. It's
not something to be rushed into because of how Subversion stores
things, and permanent removal of data from a system designed to *not*
have data removed from it needs to be done delicately.

How it that possible?

is the other case I am talking about here not the initial problem with aux. (possible other
usage in svnadmin trunk)

The increase in space has to do with how Subversion implements copies.
IIRC, if you remove the "right" parts of your history, you can end up
with duplicated items instead of cheap copies, thus increasing the
space needed to store it.
