[Xen-devel] call to xs_unwatch() does not return

[JG <javagrande2@xxxxxxxxx>]

Hi,

I have a question about the xenstore xs_unwatch() call - are there any conditions under which this call would never return ? 

I am using GuestVM [http://labs.oracle.com/projects/guestvm/] -  a JVM implementation that runs as a DomU on Xen. The GuestVM debugger runs in Dom0 and talks to the GuestVM DomU using xenstore. After establishing initial connection with GuestVM, the debugger makes a call to xs_unwatch(), from which it never returns.  

My very limited knowledge of xenbus/xenstore prevent me from debugging further and from asking a more informed/precise question.

Any help would be greatly appreciated.

My system config is as follows:

Xen version: 3.4.2
Dom0: Centos 5.4 , 64 bit 2.6.18-194.8.1.el5xen kernel.
