Ok. so maybe the way to "bisect" this is to play with that.

For example, does it happen even if the "something" does not have a
slash in it? IOW, you just append, say, a single 'a' character to a
name that doesn't already end in a slash?

And if it still does happen with that, perhaps you could have some
logic that only appends the 'a' to names that end with numbers. Does
it stop happening?

The machine keeps running, right? So you can try this out without
rebooting, just changing when you append the character?
