Distributed rendering strange behavior

[gonsolin]

Hi !
Two days ago i've calculated images with ditributed rendering without any problems (max2016, vray 3.50.03).
Today, opening the same scene i can't anymore use DR.

What's happening ?
The servers loads the scene, starts the frame, even are used for irradiance map but after that when rendering the server's buckets don't resolve (still pixelated but don't clear up) and even worst:
New "locked servers" buckets continue to be added since the main workstation still render alone... it ends with a locked rendering process and an image where only the mainstation parts are calculated.

I've tried it back in 3dsmax 2014 and it worked perfectly.
Any ideas please? I've tried so many things and now I'm stucked...
I need this to work to achieve my renders in time! Please any help would be welcomed !

Some more infos: win 7 pro, max 2016 SP4 on all stations, vray 3.50.03 and 3.50.04 tried with same result.

EDIT: added a pic to illustrate the problem (PC2 unsolved buckets are the DR server)

EDIT2: Argh ! Tested with other scenes and they are working ! That mean something's in the scene is causing that bug but what ?

Could you try resetting your V-Ray settings(by switching to scanline or mental ray and then revert back to V-Ray) on this particular scene. Then try setting up V-Ray manually and make test render. Make sure that all machines have the same V-Ray build installed on them.
