Urgent help - unexpected exception in network render

[tricky]

Anyone have these problems? I am sending jobs to our renderfarm that are to calculate the IR map only on a number of camera paths. When I come in in the morning, I find that every now and again, there is an 'unexpected exception in the network renderer and it is terminating'. This happens on all my PCs and means that the solutions that it has been building up for all previously rendered frames are lost!

I don't know where to start looking for possible problems - the message doesn't give me any clues.

Any suggestions? This is MAJOR as I have stupid deadlines to get lots and lots and lots and lots of animated frames done!!!!

Aaaahhhggghhhh

Don't know if anyone managed to read this, but I have a follow up question.

Windows XP supports up to 10 simultaneous connections. My network has 6 rendermachines, 2 workstations, the backburner manager machine and a file server.

That takes me to 10 in total. When possible, I always make the workstation machines run backburner server as well to give max rendering power.

We also have a network firewall and router that have their own IP addresses. Are this classed as two 'connections', which would occasionally take me over the limit of ten machines to 12 whenever all machines are trying to access something at the same time?

If this is the case, this could explain the above 'unexpected error'.

Any thoughts?

in your case probably thats not the problem, we had the same thing in the offise and when run into this problem the error was :"no more connections can be made" and generally the image would render without textures.
Unhandled expeption is eather a memory issue when program runs out of ram...where windows allocates only 1.7 gb mem per program, or something else like bad geometry in the scene or such.

Using Xeons and Hyperthreading? If you are disable HT, it seems to be causing problems.

Yes - HT was the problem - see recent posts. VRAY is just not stable with HT.
