Public bug reported:
Binary package hint: gnome-terminal
After long usage of gnome-terminal without terminating the process,
gnome-terminal gives "too many open files" error when open a new
terminal.
Looking at the /proc/xxxx/fd, it seems that all opened /dev/pts/xxx and
/dev/ptmx are left unclosed when an terminal window/tab is closed.
what I get from /proc/xxxx/fd is hundreds of opened fd

to reproduce, open gnome-terminal, open a new tabe by ctrl+shift+t, then close
the newly opened tab, then look at the /proc/xxx/fd, you can see the newly
opened fds are left unclosed.
After a long run with frequenct open/close of terminal, you'll "too many
open files" error
