Thanks Greg, both were helpfull. Maya Mental Ray rendering is definitely finicky. So setting the nodes to only process one render at a time and fixing the temp directory made all my issues go away.

Once we migrate to Maya 2012 I will see if I can switch it back to 4 renders per node.

Thanks again!
Jeff

	Yes, it looks like your .common.pl file is from an old release
	(about 5 years old) and did have a problem.

	I suggest this line near the top of the file (on or around line 38):

chdir($G::tmpdir);

	..be changed to instead read:

if ( $G::iswindows && !defined($ENV{RUSH_TMPDIR}) ) # windows: prevents complaints from DOS { chdir($G::tmpdir); } # about cwd being a UNC path

	This ensures that during render time, if the renderer decides
	to write to the current working directory, it will do so in
	the RUSH_TMPDIR instead of eg. /var/tmp.

	Not sure if that will help, but it might.

	If it doesn't, see if limiting renders to only one render
	per box solves the problem, as it might be the case maya
	is creating temp files that are overwriting each other when
	more than one render runs on a machine. Every once in a while
	renderers have that problem, then they fix it, then years later
	repeat it again :(
