[Barrelfish-users] Bindings

I'm really stuck on a problem cause I can't figure out its source. The bottom line is that a client freezes while waiting for a reply from the bind operation on the server's iref. Let me elaborate on it...

There is a primary instance of the server which spawns multiple other instances of itself as separate applications. Each of them gets a binding to each other, thus creating an interconnected distributed service. Communication between them provably works.

The client comes up, successfully retrieves the primary server's iref from the nameservice and executes the bind operation on it. Right afterwards it executes the "messages_wait_and_handle_next()" function to wait for the bind's reply. The reply's handler is set as the continuation to the bind call but it never executes. At that point everything freezes. If I omit the "messages_wait_and_handle_next()" then the client will proceed normally without ever having the bind's reply execute.

Any hints or ideas would be mostly welcome. Thanks.
