Rendering Fumefx with vray 2 sp1 sometimes leave empty buckets

[larex39]

I dont know what starting this problem but sometimes when i render fumefx it leave randomly distributed black buckets (i dont use distributed renderig). This newer happens with internal build of vray 2.03. i cant repeat this error but sometimes it occour. Im using fume 2.1a and 3dsmax 2011 x64

Do you have a scene that we can use to test?

It is not specific to scene it is doing sometimes, and i cant reproduce it. Now I realized that im doing only fumefx renders so maybe it can happend also with normal rendering, and Im using remote license server so maybe if you changed something also there it produce this problem, strange is that it never happend before sp1 to me.
