I set up an animation of 36 frames, each which was taking ~20 minutes to render.
When I returned hours later, I saw that the render bombed for a message of
"Operation timed out."  The screen was highlighting an include statement.  I
hadn't touched the PC, so the "timed out" shouldn't have been different from
frame to frame.

Without presuming of the windows port, there is a single place for such
error (at least for a unix port): povms.cpp, circa line 883.

It's in POVMS_Send.

Default timeout is 10 s, but in case of _DEBUG defined, vfe/vfeconf.h
define it to 100 s;

As far as I can see, the timeout is a POVMS property ('TOUT') but is not
settable per ini file.
So, you get stuck 10s (of wall time) and the POVMS system get no
progress on its messages...

What is at the line 39 (and around) of
"C:\$user\pfa_demo\gini\subsurf_mh_f11j.pov" ?

Is the file included on a network drive ? (auto-umount ? any
screen/power saver ? (turn disk off after xx minutes of inactivity ? no
mouse movement-->inactive... ))

Line 39 is:

#include"transforms.inc"

The file was on the HDD, in the same directory. There wasn't anything different
for this frame than any others.  If it matters, I've done lots of long term and
overnight renders with this computer and never run into this error before. The
differences are RC3 (I am a latecomer to 3.7, having used MegaPov until just
recently), and that this project had each frame much longer-rendering than most
of those I'd done in the past.

thanks.
