After a bit mor testing of t_replicate_udp I am sorry to say that we still have a problem with that. Firewall is open. We see the same locked transactions and replication has stopped, the other side has an empty usrloc. Kamailio from the 5.0 branch of git before the 5.0.3 release. Version: ``` # kamailio -v version: kamailio 5.0.2 (x86_64/linux) ```
``` # kamcmd tm.stats { current: 19974 waiting: 19974 total: 534594 total_local: 0 rpl_received: 544239 rpl_generated: 577 rpl_sent: 534606 6xx: 0 5xx: 4533 4xx: 584 3xx: 0 2xx: 529484 created: 534594 freed: 514619 delayed_free: 0 }
```
One server replicating with udp, the other with tcp. I see TCP keepalives flowing, so no blocking any more.
