Andy,

The fix committed under revision r441691 fixes the occasional server 
crashes. This was not related to Web Services, it was a problem with 
ComponentContextImpl::~ComponentContextImpl() aggressively deleting 
proxies that it had served. Proxies need to live longer than the context 
that served them as they can be passed around to other components for 
example.

With my change, CPP proxies are now deleted when the CPPServiceProxy 
object that created them gets deleted (and this will eventually happen 
when the instance of the current Composite gets deleted, right now I 
don't think that the destructors do all the necessary clean up, but this 
is a more minor issue).

Let me know if you still see these occasional server crashes, this 
change seemed to fix them in my environment at least. Thanks...

Hi Sebastien,

Those changes fixed my problem - no more server crashes!
