Application Crash with large scale data. Error:DDS.Retcode_OutOfResources- virtual sample not found

I have CAD application where i am tring to publish and subcribe from one CAD machine to other CAD machine. I can able to publish and subscribe the data but when i work with same application for a day , there was only one instance where I saw the CAD got crashed.I can see following exception been created

Control Communications with DDS using IEC61499 Service Interface Function Blocks

https://ieeexplore.ieee.org/abstract/document/5641207

The IEC61499 is an open standard for distributed control and automation. The interface between control software and hardware or communications is achieved by means of the so-called Service Interface Function Blocks (SIFB).

Describes the devekopment of UAV Control Station by Raytheon:

  • The control stations provide command and control of an unmanned air vehicle (UAV)
  • A common control station controls more than one type of UAV
  • A control station is made up of a set of service
  • Services defined by the Unmanned Systems (UxS) Control Segment (UCS) Architecture standard. Some common to all vehicles and some unique to a single vehicle

UAV Control Systems belong to a class of systems that require:

Late-Subscribers not receiving DDS Messages LabVIEW

 

My project involves using RTI DDS (v2.2.0) in multiple different LabVIEW applications, some of which are running on the same PC and some of which are running on other PCs or RTs.  My goal is to have each application keep a record of all applications that are currently communicating on the same DDS Domain.

Future Proof IoT: Composable Semantics, Security, QoS and Reliability

https://ieeexplore.ieee.org/document/7878740/

IETF impressively defined internet interoperation across 30 years of unforeseeable syntax API. IOT needs similar future proof, but for connected things' composable semantics, security, reliability and Quality of Service (QoS). This paper overviews these with simplifying tradeoffs from a bottom up approach using Data Distribution Service (DDS). Then high level semantic additions to DDS are suggested for semantics that are backward compatible, while maintaining the security, reliability and QoS of DDS.

Distributed Simulation Using DDS and Cloud Computing

https://dl.acm.org/citation.cfm?id=3106388.3106391

NASA Langley Research Center identified a need for a distributed simulation architecture that enables collaboration of live, virtual, and constructive nodes across its local area network with extensibility to other NASA Centers and external partners. One architecture that was prototyped and evaluated employed Data Distribution Service (DDS) middleware and the GovCloud cloud computing service. The nodes used DDS to exchange data.

An investigation into some security issues in the DDS messaging protocol

http://ro.ecu.edu.au/ism/215

The convergence of Operational Technology and Information Technology is driving integration of the Internet of Things and Industrial Control Systems to form the Industrial Internet of Things. Due to the influence of Information Technology, security has become a high priority particularly when implementations expand into critical infrastructure.

Applying MBSE to the Industrial IoT: Using SysML with Connext DDS and Simulink

Submitted by Gerardo Pardo on Tue, 07/03/2018 - 11:12

The benefits of Model-Based Systems Engineering (MBSE) and SysML are well established. As a result, users want to apply MBSE to larger and more complex Industrial IoT applications. 

Industrial IoT applications can be very challenging: They are distributed. They deploy components across nodes spanning from small Devices to Edge computers to the Cloud. They often need mathematically-complex software. Moreover, they have strict requirements in terms of performance, robustness, and security.
