Can anyone make sense of this? Even better, suggest how to fix it? I
am running povray3.5 under w2k on an Athlon 650 with 512 mb of ram. My
photons block is as follows:
photons {
count 100000
media 100 // media photons
max_trace_level 5
save_file "fotons"
autostop 0
}

You're using more photons than your computer can handle. Reduce the total
number of photons to as little as is necessary, and *especially* reduce the
maximum number of media photons to the minimum necessary.

But how can that be? I would expect the hard disk to start thrashing if
that was true, but not a error code.

Perhaps you've run out of disk space or don't have virtual memory set up
right? Also, IIRC, photon tracing is fairly quiet in its use of virtual
memory -- the serious thrashing doesn't start until POV-Ray begins
sorting photons.

See my post in p.g "Snail racing is more exciting" on 25 Aug 02.

So in other words it is still something of a mystery. The 327680 must
be more than mere coincidence eh?

Searching the web view of news.pov turned up a number of posts with
this error but no definitive answer.
An entrant in IRTC around 1998 (?) said turning off light_buffer
solved his problem.
Google gives a number of links that show other applications have this
error. In some cases memory was stated to be available, but again, no
explanation that I understood.
I have 160MB, Win98SE and around 9 gig free disc space. In my case,
photon count in the stats line increased to around 78K in about 6
seconds and pov then froze for a few hours before giving up. No disc
operation was evident.

Yes, photon storage is allocated as blocks of 16384 each and each photon
requires 20 bytes. You just run out of memory. Nothing special to it.
