Package: emacs22
Version: 22.2+2-5
Severity: normal
Emacs 22 seems not to close TCP sockets for connections to X11 servers
that have died (as far as emacs is concerned). This leaves those
connections in CLOSE_WAIT state. Which consumes kernel ressources and
pushes emacs towards its maximum file descriptors limit, etc.
The exact scenario where I hit this bug is:
- run an emacs on host A
- "ssh -X" from B/C/D/... to A
- open an emacs frame (e.g. through gnuclient or
"M-x make-frame-on-display") on that SSH connection.
- close that frame
- close the SSH connection
- emacs does not close the corresponding socket, and netstat shows
the connection as CLOSE_WAIT.
Lather, rinse, repeat. Eventually, emacs cannot open files / network
connections anymore ("ulimit -n" limit reached).
