Hi Daniel,
More information. I'm attaching the log (with debug=2) between the dispatcher nodes
down & up at the time of the problem.
[kamailio_sbc_2.log.txt](https://github.com/kamailio/kamailio/files/1117574/…
Some extra stuff:
1. There is a gap a little bit after the dispatcher sets the nodes down, until a little
before the dispatcher sets the nodes up, hope this helps.
2. We use VoIPmonitor and the sensor receives the traffic from a port mirror on the
switch, in the timeframe of the issue, there is no traffic detected from the affected
server.
3. We pull performance metrics from Kamailio every 10 seconds using xhttp and json-rpc
modules, during the issue our tool can't pool metric either:

```
I will leave the tcpdumps enabled anyway in case next time it happens we can get more or
better information.
Joel.
