Can you do some experimentation to try to narrow this down? For example:

emacs-X11 also?

Is starting up Tramp and then leaving emacs idle sufficient?

Ken
The problem seems specifically related to TRAMP. I opened up three emacs-w32
sessions, with the following settings:
* emacs-w32, no TRAMP
* emacs-w32 -Q, TRAMP
* emacs-w32 -Q, no TRAMP
and left them running in the background. Only the session with TRAMP has
aborted so far. The backtrace for the abort from GDB is shown below:

Another error also occurred in the same session a few hours prior to the abort.
Something about a wrong argument type error with vectorp and timers. I'll use
the Lisp Debugger to get more information next time.
I'm currently using emacs-X11 with TRAMP (no -Q flag) for my main work. I've
seen the same Lisp error after leaving this session idle, but so far no aborts.
As for the minimal sequence of steps that leads to the abort, I use Dired on a
remote directory via ssh with TRAMP and open up a file for editing using the
Dired buffer. I then leave the session idle and minimized. I occasionally check
on the session to see whether a Lisp error has occurred. The abort dialog
pop-ups after enough time, but I haven't pinpointed exactly how long. I'm going
to run more tests so that I can give you a more specific sequence of steps.
From the BLODA, I have Symantec Endpoint Protection 12.3 and NVIDIA Graphics
Driver 266.72 installed. The Symantec software is current, but I'm going to try
updating the NVIDIA driver to the latest version.
Cheers,
SDS
