Also looks as to this issue relevant to another use case.
After call established on RTPengine host I execute
```
rtpengine-ctl set maxsessions 0
```
Now when Kamailio receives ReINVITE in Kamailio log I can see
```

According to logs rtpengine Kamailio module
1. do not use other available RTPengine nodes, during a test available another RTPengine node;
2. send again and again request to same failed not available RTPengine node.
