Dear Maintainer, This may not be Konsole's bug.
By deep dive into the problem, I found those redundant FDs were coming from kwin_wayland, the wayland implementation of KWin. Today I tried to start a Konsole Terminal in another desktop environment rather than KDE Plasma, and the redundant FDs problem did not reproduce this time. So you may close this bug ticket.
