Nxt crashing

[Peter Hoffmann]

I just got a new computer, AMD FX8150 8 core, 16 gig ram running Autocad 13.

Problem is my renderings keep hanging up anywhere from a few minutes to 4 hours after i start them.

this morning I tried to reinstall NXT but aborted accidentally.  Now I cant even reinstall it, keep getting the following msg:

An error occuredd during the installation fo assembly 'Microsoft.VC80.CRT, type="win32.version="8.0.50727.6195".publicKey Token="1fc8b9a1e18e3b".processorARchitecture="amd64".please refer to Help and Support for more information. HRESULT:0x80073715.

have a deadline today, running out of options.

Haven't seen this before (at least not that I can recall.)  Microsoft appears to a have a hotfix for it.  You'll need to contact them using the link below.  This sort of thing tends to happen when the configuration on a machine is screwy-- perhaps due to viruses or malware.  The render hanging problem, of course, tends to suggest that something else is wrong as well.

At this point I have done the following:

We have reinstalled Autocad both on the machine discussed above and on my own machine (intel 3770k  CPU)

Have reinstalled NXT on both.

Both machines are virtually new and free of viruses.

I have tested files that ran fine under Autocad 2012

Keep getting same problem, either Autocad crashes or whole machine locks up between 30 minutes and 7 hours into renderings.  Have tried batches as well as just letting one rendering run overnight.

So at this juncture it seems that the problem lies with Acad2013 and Accurender combo.

Not sure how to proceed.  Attached is picture of this mornings lockup showing running time of 2 hrs plus before it died.

There isn't much I can do here unless I get something reproducible.  The problem isn't happening generally, we would be hearing about this a lot if it were.

You are rendering at an exceptionally high resolution.  While this should not cause a crash, 21 MPixels are almost always overkill.  Try seeing if some low-res renderings survive the night to see if the problem lies there.  It would be a start anyway.  Display driver software, heat management, are all remote possibilities.

[Peter Milner]

Most new computers have power management settings which sometimes conflict with the graphics card requirements. In other words, the computer doesn't supply enough power to the graphics card. This happened on my machine as it kept crashing after a certain amount of rendering time.

[Peter Hoffmann]

We are investigating.  is the processing all done on the CPU or is the GPU involved as well?  We are using Quadro 2000D.

[Roy Hirshkowitz]

No GPU processing per se-- but the video card will always be a (small) part of it since it manages the display.  I'm somewhat concerned here since it's happening on multiple (different) systems.  If they have the same GPU then perhaps updating drivers may help.  I would still try a low-res overnight test to see if it makes a difference.

[Peter Hoffmann]

made a simple model file and ran it at low res last night.  same results.  attached are pics of the two monitors as they were when machine froze.  was running task manager and the performance graphs.

[Roy Hirshkowitz]

3000 x 1500 is not low-res (!!)-- run one at 640 x 480, for example, if you want to exclude memory from the problem.  (12,000 faces, BTW, is not a simple model either).

There are usually some heat management settings you can toy with-- setting the processors to run at 97% capacity, for example, usually solves any excess heat minimal performance degredation.  However, I don't really think it's heat-- that normally brings the whole machine down and causes a reboot or shutdown.

Best guess at the moment is the display driver or some hardware management setting as Peter described.  Only a guess, though.

Roy,

 

Ran the small render last night.  Crashed 4:44 in.  Also trying to run next on 2012.  NXT loads fine, but as soon as I try to attach a material it crashes.

[Roy Hirshkowitz]

Bizarre.  Just for grins give me the exact steps you use to produce the error in 2012.  64 bit I assume?  If a drawing is required to reproduce please send it.

[Peter Hoffmann]

Roy,

Still having the same issues.  Has anyone else had similar issues.  At this point machine just locks with fans spinning on high.  somewhat at an end here.

[Roy Hirshkowitz]

Which issues? Be very specific, you mention two different ones above.  For example, does it still crash in 2012 when attaching a material.  If so, this is one I can probably look at if I can reproduce it here.  I'll need very specific steps before I can test it.  Hanging after hours of rendering is likely (but not necessarily) a hardware/OS problem.  Have you tried the heat management settings-- hanging with fans spinning suggests a heat problem.
