Problem with custom rm-service

[David Werner]

Hi Genode mailing list,

the last few days I wrote a server component (called proxy_server) which 
offers a custom RM-service called "PRM" (Proxy_RM).

Under the hood the component maintains a Rm_connection within each 
Prm_session_component in order to use the original core rm_service. My 
aim is to intercept all attach and detach operations.

Compiling and linking works perfectly but when I run my system scenario 
(on foc_x86_64) I get the following output:


Genode 15.11-71-g2e0e767
int main(): --- create local services ---
int main(): --- start init ---

Error: Test execution timed out

I do not understand where the output:

Genode::Signal_session_component::submit(Genode::Signal_context_capability, 
unsigned int)::<lambda(Genode::Signal_context_component*)>: invalid 
signal-context capability
Genode::Pager_entrypoint::entry()::<lambda(Genode::Pager_object*)>: 
Could not resolve pf=401feff8 ip=100b9af

comes from.

Is there anyone who can help me with this or who has an idea what I can try?

If needed I can post my code here.

Best Regards,

David
