v195 is five years old, already on the far end of "unsupported". It's
likely that the leak has been fixed long ago. If you absolutely cannot
upgrade, see if you can find something relevant in post-v195 commit logs.

My only guess is that each connection results in a new unit (maybe a
.scope, or an instance of user at .service, or... whatever existed back then)
and those are not properly garbage-collected later.
