Bad Vray bug, workstations and farms crash and freeze

I have 7 dual quadcore xeon series 5XXX with 8Gb each, Intel vernonia motherboards with the latest firmware.

In some Max scenes with a lot of glass materials Vray 1.5Sp4 (Sp5 too) crashes and freeze some of my networked farms. I have to push the power on-off to restart the machines. All my farms are well ventilated with air conditioning, all ram banks are Kingston ECC.
I’m a Indigorender user too and with this software I can render on all farms without crashes for many hours or days without interruptions and with scenes that surpass 6Gb and full throttle processors.

What’s the Vray problem?

Best regards.

maybe its not Vray. Maybe its your router or internet cables that are overheating. Im guessing u are moving a lot of data, lots of calculation. About Vray, well I have no idea what it could be tbh… Id blame it on hardware :slight_smile:

btw is it always that same workstations that die or is it random >?

V-Ray cannot cause a system freeze or crash by itself. Such issues typically indicate hardware problems with your machine(s), especially if they are overclocked. The worst that V-Ray can do is crash the 3ds Max application only.

As for other applications/renderers, it could be that they don’t stress the hardware (CPU/RAM) in the same way that V-Ray does, so this is not a very good comparison.

the problem happens always on the same farms, 3 on 4, but they are identical, same hardware, same components except for the video boards. Could the video board crash a farm during the render?

make sure that you have the same service packs, hotfix, etc in Max as well as windows…I would check if the memories were well installed ( physically )
swap the memories (all together) with other computers to check if they running ok so you could see if is hardware problem(RAM)

ok I will check memory banks and swap them…all o.s. are windows xp64 with latest updates

thanks for your suggestions

Best regards

I suggest that you get memtest86 and let it run a full test cycle. http://www.memtest.org/ If you have bad RAM, this will find it.
