memory increase

[gzbf666]

Is there an already existing issue for this?

Expected behavior

when create subscription within a loop(as 10000 times), the memory should be stable.

Current behavior

when create subscription within a loop, the memory keeps growing to very large.

Steps to reproduce

class HelloWorldSubscriber
{
~HelloWorldSubscriber()
{
sub->delete_datareader(reader);
participant->delete(topic);
particitpant->unregistger_type(type.get_type_name());
DomainParticipantFactory()::get_instance()->delete_participant(participant);
}
init()
{
participant = DomainParticipantFactory()::get_instance()->create_participant(qos,0);
sub = participant->create_subscriber();
topic = participant->create_topic();
reader = sub->create_datareader();
}
};

int main()
{
HelloWorldSubscriber *ar[40];
int count = 10000;
while(count-->0){
for(int i = 0; i <40;i++)
{
ar = new HelloWorldSubscriber();
if(ar) ar->init();
}

std::this_thread::sleep_for(std::chrono::seconds(1));

for(int i = 0; i < 40; i++)
{
delete ar[i];
ar[i] = nullptr;
}
}

return 0;
}
