Hi,
We are experimenting with the rticonnextdds_connector with node.js. Due to some legacy reason, we need more than 10 participants from different domains. However, node.js has a single process. On our 64-bit Ubuntu 14.04, the maximum number of participants was limited to 8.
In order to increase the number of participants, we would have to change the resource_limits.max_objects_per_thread of DDS_DomainParticipantFactoryQos. The api to access DDSDomainParticipantFactory is not exposed in the connector.
