AS behaves strangely when deploying Seam projects

I have encountered strange behaviour of AS when testing Seam 2.0.3.CR1 recently. To reproduce follow these steps:
a) deploy Seam booking example
b) some interaction is needed so book some hotel
c) undeploy Seam booking example
d) deploy Seam drools example
example starts to deploy but at some point it hangs and looks like nothing is happening - no messages being appended in log not even debug messages however I noticed heavy disk usage. Usualy after waiting more than 10 minutes second example is still not deployed. It happens in both Seam 2.0.3.CR1 and Seam 2.1.0.CR1. Same situation with registration and itext example. Issue may be caused by problem with undeploying the first example. in some cases second example gets deployed after several minutes.
