Subscriber freed and restarted : no data received

Hello,

In my project, I need sometimes to destroy a subscriber and all its related datareaders, to instanciate them again after with the same parameters, without changing anything with participant.

The environment is .NET 4.0 / RTI DDS 5.1.0

Here is the sequence :

---subscriber intialization---

sub = participant.create_subscriber(SubQos, ...);

...

DataReader reader = sub.create_datareader_with_profile(SomeContentFilteredTopic, ..., DDS.StatusMask.STATUS_MASK_ALL);

...

reader.enable();

sub.begin_access();

SubQos.partition.name.ensure_length(1,1);

SubQos.partition.name.set_at(0, "*/somePartition");

sub.set_qos(SubQos);

---End of initialization---

--- Subscriber shutdown ---

DataReaderSeq seqDataReaders = new DataReaderSeq();
m_oSubscriber.get_all_datareaders(seqDataReaders);

for (int i = 0; i < seqDataReaders.buffer.Length; i++)
{
        m_oSubscriber.delete_datareader(ref seqDataReaders.buffer[i]);
}

m_oSubscriber.end_access();

m_oSubscriber.delete_contained_entities();

--- End of subscriber shutdown ---

The problem is :

I can intialize and then shutdown my subscriber twice. Then, on the next initialization, my subscriber and its related datareaders won't receive any data.

Admin Console detects the subscriber and its related readers without any problem each time the subscriber is initialized.

When the problem occurs, the DataReaderListener methods "on_liveliness_changed" and "on_subscription_matched" are not called anymore.

Edit :

Actually, the problem is even bigger : the other subscribers stop receiving datas when a subscribers is shutdown and restarted for the second time. They're configured to listen to same data types but on other partitions, and from other publishers.

Thank you for your help,

Mathieu
