A strange problem. I run Emacs across a number of machines, with more-or-less a shared configuration.
However, on one specific machine, after some time I am no longer able to launch new emacsclient frames to make a connection to the locally-running emacs daemon. For many hours I will have no problems connecting new emacsclient to the daemon, but eventually it occurs. I usually find this after trying open a new emacsclient in the morning.
$ emacsclient -c
/usr/bin/emacsclient: connect: Connection refused
/usr/bin/emacsclient: No socket or alternate editor. Please use:
--socket-name
--server-file (or environment variable EMACS_SERVER_FILE)
--alternate-editor (or environment variable ALTERNATE_EDITOR)
Currently open emacsclient frames continue to function normally.
The opening of new emacsclient frames can be re-enabled by running (server-start), which of course kills off all of the currently open emacsclient frames.
Since the system behaves normally for some time after launching emacs --daemon (or emacs --fg-daemon, as appropriate), and since none of my other systems exhibit this behaviour, I'm at a loss of how to debug this.
