In a scenario where multiple DataWriters come up and go away in the system, a matching DataReader application will experience a continual memory growth, this may be confused with a memory leak. This observed behavior is due to the fact that DataReader entities must maintain information about the ...

RTI Connext DDS uses multicast for the discovery process in the default setting. When a host needs to join a multicast group, the network stack of the host sends out an IGMP Membership Report message also known as the join message. These messages are forwarded through the LAN to the local IGMP ...

For high-rate data, the usage of a WaitSet may lead to a very high CPU usage if the WaitSet wakes up too often. By default, a WaitSet is created without any properties specified. In this case, the WaitSet wakes up immediately every time a trigger event occurs. However, "waking up" involves a ...

Packets starting by RTPX are default domain discovery announcements. This is a new non-standard packet introduced in Connext 5.1.0 to help the tools discover applications running in other domains (for instance, RTI Admin Console). This packet is sent to the default multicast address and port for ...

For complex systems with hundreds of participants and endpoints, discovery may cause long startup times and high network utilization. There are several options that help increase discovery performance: 1) Reduce the size of discovery packets 1.1. You can configure the middleware to not send the ...

There are some situations in which two applications, even though they have been configured to have each other in their initial peers lists, will not discover each other. Two applications are on the same machine and have only either 127.0.0.1 or "localhost" in their initial peers lists AND ...
