DR - Fails to save complete scene on slaves

[murko-sk]

Hi,
we have issues with rendering large scenes via DR - if we render it on just any slave, it works perfectly, but as we add more slaves to render, the vray_server_scene.max isn`t saved whole on all slaves and DR report that slaves haven`t received the scene. In Resource Monitor in Vista we see that the vray_server_scene.max is continously saved on slave's 3ds temp directory, but never reach its full size, it stops randomly - around 2/3 of its size and then in Resource Monitor the file size is decreasing to zero.

- all machines have enough space on hdd
- the network is connected through 100 Mbps switch, and every slave have full unrestricted connection between them ( they have opened all ports, can be sucesfully pinged between each other )
- machines specs : Vista x64 SP1 on 2x 8GB RAM & Intel Q6600, 6GB RAM & i7 920


So far,

Hm, looks like something interrupts the network connection between the machines. Do you use static or dynamic IP addresses in your network?

Best regards,

Dynamic, for information - the switch is OvisLink LIVE-FSH16T+.

The IPs aren`t changing, as machines got exact IP everytime according to port on that switch they`re plugged in.

New issue - if i connect directly two machines via ethernet cable, assign static IPs, the server sent scene to slave correctly, in "vray messages" are reports of succesful scene transfer to slave & "scene loaded, started rendering", and after that the slave never participate on rendering, nor in prepass, nor in beauty mode.

i used to have this bug once.....the render was flagged finished just after its start on the slaves...
i started from scratch in a new scene and merged only geometry from the buggy scene.... it worked. i never understood what happened.
