V-ray choking on light cache with textures over certain size?

[Richard7666]

V-ray seems to hang for 5-10 minutes when using particular textures. All they are are a pair of resized (4000x2000, 2mb) textures from Arroway. V-ray gets stuck at these textures

before proceeding with the light cache as usual (which itself takes a long time to calculate. Displacement causing a problem maybe?)
The scene consists currently of nothing but a ground plane with a grey vray material, and a wall with my displacement vray material. Nothing amazingly special about it.

Maya 2013, V-ray 2.30.01

any ideas? It makes test rendering a bit of a pain for this particular scene : /

It would be best to send us a sample scene to vraymaya@chaosgroup.com so that we can check what's going on.
