VRay framebuffer (VFB) crashes

Recently I’ve been getting frequent crashes when using the VFB, whereby Maya will crash out completely either at the end of a render, or if the ESC key is pushed during a render. These crashes got progressively more frequent to the point that I couldn’t successfully complete even one render. Eventually found a solution (here) by removing the block in the Maya ASCII beginning “setAttr .vfbSA”. In my case, this block was several thousand lines long (this section of the .ma file is attached in case it’s of any use). Is there an easy way to fix/avoid this problem? Everyone in my office has it to some degree. Thanks.

Edit: OK, so using the “Reset V-Ray VFB” option in Render Settings fixes this, but obviously resets everything, so the question really becomes is there a way to avoid the VFB becoming corrupt?

Using VRay 3.4006, Maya 2016e2, Linux

Thanks for the file. It looks like the huge size comes from the LUT settings. Would it be possible for you to send us the LUT file as well?
