[omniORB] (no subject)

[Stefan Kimmig]

Hello,

I am using OmniORB 4.1.3 on an AT91SAM9263 processor with realtime kernel 2.6.29.1-rt8, but i got the following problem:

I want to build an soft rt application which communicates via omniorb. This application should be a server and a client at the same time. At the beginning of the application I lock all the memory with the mlockall() command. When I run the application the size of locked memory gets higher and higher and after some time, the processor runs out of ram. Is there a problem of using omniORB in rt application or has anyone tested omniorb in a realtime process?

here ist my programm code: 

int main(int argc, char* argv[])
   {
       // Allocate some memory
       int i, page_size;
       char* buffer;

       mlockall(MCL_CURRENT | MCL_FUTURE )
       
       // Turn off malloc trimming.
       mallopt (M_TRIM_THRESHOLD, -1);
       
       // Turn off mmap usage.
       mallopt (M_MMAP_MAX, 0);
       

       page_size = sysconf(_SC_PAGESIZE);
       buffer = malloc(SOMESIZE);
       
       for (i=0; i < SOMESIZE; i+=page_size)
       {
           buffer[i] = 0; 
       }
       free(buffer);
       
       CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
       CORBA:Object_var obj = orb->resolve_initial_references("RootPOA");
       PortableServer::POA_var poa = PortableServer::POA::_narrow(obj);   
       Echo_i* myecho = new Echo_i();
       PortableServer::ObjectId_var myechoid = poa->activate_object(myecho);
       obj = myecho->_this();  
       CORBA::String_var sior(orb->object_to_string(obj));  
       cout << (char*)sior << endl;
       PortableServer::POAManager_var pman = poa->the_POAManager();
       pman->activate(); 
       


       return 0;
   }
