Physics Warning "WriteLock is still acquired"

Hi,
I've a problem with PhysicsShape.
I try to setting datablock and position with setDataBlock and setTransform methods but sometimes appears a warning:

PhysX Error:
D:swphysxPhysXSDK2.8.4trunkSDKsPhysicssrcNpActor.cpp(412) : PhysicsSDK: NpActor::addForceAtPos: WriteLock is still acquired. Procedure call skipped to avoid a deadlock!

This is the code:

sceneOwner->inspectPreApply();
sceneOwner->setTransform(mat);
sceneOwner->inspectPostApply();

obj->inspectPreApply();
obj->setDataBlock(pData);
obj->inspectPostApply();

Help me!
