(setq debug-process-io 1) helps a lot. I see now that when I press Done, gnuserv fails in send_string with a bad file descriptor. In my case the descriptor is 5.--On Wed, Apr 12, 2017 at 8:39 AM, Raymond Toy <toy.raymond@gmail.com> wrote:I built the ToT version on Ubuntu 14.04 and everything seems to be working fine except for one thing.I start xemacs, and the M-x gnuserv-start. In a terminal, I run "gnuclient file". Edit the file in a new window as usual and press the Done button. Window is closed and everything seems fine, but in the main xemacs window, the minibuffer says that gnuserv exited and to M-x gnuserv-start again.This didn't used to happen. Can't figure out why gnuserv is exiting in this way. Any tips on figuring this out?--RayRay
