 | Hi Honorato,
Thanks for help. I did several tests, including connecting just the
supplier, but the error remains.
By the way, the Kokyu example
($TAO_ROOT/orbsvcs/examples/RtEC/Kokyu/Service.cpp) connects in
following sequence:
1) Events consumers
2) Events suppliers
3) Timeout consumers
and all works fine.
What is different in my scenario:
- I'm using a POA created from CIAO containers'POA
- Event channel, admins and proxies references are passed by method
arguments. I mean:
1) Server Object: contains Event_Channel_var reference and passes it to
Session object:
ACE_NEW (session_i, Session_i(this->event_channel_.in())
2) Session Object: gets the event_channel reference in constructor:
Session_i::Session_i (RtecEventChannelAdmin::EventChannel_ptr ec) :
event_channel_(RtecEventChannelAdmin::EventChannel::_duplicate(ec))
and obtains the consumer_admin and supplier_admin. The admins references
are passed to another object:
ACE_NEW (manager_i, Manager_i(this->consumer_admin_.in(),
this->supplier_admin_.in())
3) Manager Object: gets the admins references and creates the proxies
Manager_i::Manager_i (RtecEventChannelAdmin::ConsumerAdmin_ptr ca,
RtecEventChannelAdmin::SupplierAdmin_ptr sa)
The manager object uses the admins references, creates the proxies and ,
when trying to connect only the supplier, the segmentation fault occurs.
I don't know if all this reference's travel makes something wrong, but
consumers are connected fine.
Any suspicion ?
Thanks,
Sandro
