The error message says that the receive side (the server) did not
provide storage space for the message.

Change that to
struct SERV : L4::Kobject_t<SERV, L4::Kobject, 0x44, L4::Type_info::Demand_t<1> >
to specify that the server can also receive a cap.

Please check your compiler warnings, this misses the third parameter and
thus the error message is confusing/wrong.

The protocol number of the interface, some unique number that should not
clash with other interfaces used for a channel.
