emacs --daemon and emacsclient issue

[Noorul Islam <noorul@noorul.com>]

With last weeks trunk build "emacs --daemon" is behaving in a strange
manner. I usually run "emacs --daemon" and then use "emacsclient -c"
to have any number of frames. But now what happens is, when I lock my
screen, after certain period my frames get closed automatically. But
"emacs --daemon" process is still running. If I try "emacsclient -c"
again, I get socket not found error asking me to start server again.
Anyone else facing similar problem? Since I no longer able to
communicate with the server I could not figure out for what reason it
broke. strace on the daemon is also not helping.

Thanks and Regards
