V-Ray V-Ray for Maya General
1

Hi Guys,

I’m getting the error in the title and just don’t know what to check anymore:

I have this setup:

A linux server where the vray license server is running.
5 Imac’s with maya and vray installed
1 of those is my workstation from where I start jobs which have DR enabled,
I have added the other four (static) ip’s in the maya DR settings list.

1 of the machines (192.168.1.12) always gives the above error, one of the others ( 192.168.1.18 ) sometimes.. the other two never give any errors. I can ping all the machines from my workstation.
On every machine vray.exe is running, i pointed to the license server correctly..

Sometimes i get black blocks in my render, but other times not..
on every machine i enabled, wake on lan if they are asleep, actually i even disabled sleep..

when I batch render I can see in the log that vray starts using 3 hosts for DR, but then during rendering irradiance or light cache, some of the hosts won’t respond anymore and the render fails..(blocks..)

can you guys help me solve this?
:smile:

Which V-Ray build is this?

Best regards,

from the log:
V-Ray for Maya version 1.50.SP1 from Jun 11 2010, 17:05:34
V-Ray core version is 1.90.03

I just made a render that used all four of the hosts, including the one that wouldn’t render (192.168.1.12) but now no hosts will join the DR render:

hmmm… it appeared our license server stopped working, when i checked the status page of the license server the DR licenses were maxed out at 10 but we only have 4 hosts.
when we tried to restart the license server it appeared that 2 deamons were running??

we then tried to kill see log:
