Re: [SR-Users] DMQ problems

Hi Aleksandar,

The initial depopulation of the nodes (following a period of 'pending' state) is due to no response being received from them. Are you able to trace the messages to/from one of them to confirm what is happening there?

As for the unrecognised IP, I'm afraid I can't answer that one. It must be coming from somewhere - it's just a case of finding out where. Following the initial population/depopulation of the node list, DMQ simply repeats the process over and over until it eventually connects to one or more other nodes. Are you running on a public cloud somewhere or is it your own, locally running Kubernetes cluster?

Cheers,

Charles

Hi Charles,

We're so glad about the improvements you just committed! Thanks!

Now I'm using the latest nightly: 5.2.0~dev6+0~20180726010431.1165+xenial Kamailio starts even if the DNS record does not exist at first, that's great. I'm having this nodes up and running:

proxy-66f79498cc-8ws6d                3/3       Running   0
4m        172.28.1.4
proxy-66f79498cc-b68dd                3/3       Running   0
4m        172.28.1.5
proxy-66f79498cc-lhbxg                3/3       Running   0
4m        172.28.1.6
proxy-66f79498cc-png6p                3/3       Running   0
4m        172.28.1.7

In those 4-5 minutes I've experienced a population and depopulation of the dmq nodes.

For example:

kamcmd> dmq.list_nodes
{
host: 172.28.1.4
port: 5061
resolved_ip: 172.28.1.4
status: pending
last_notification: 0
local: 0
}
{
host: 172.28.1.6
port: 5061
resolved_ip: 172.28.1.6
status: pending
last_notification: 0
local: 0
}
{
host: 40.100.109.113
port: 5061
resolved_ip: 40.100.109.113
status: pending
last_notification: 0
local: 0
}
{
host: 172.28.1.5
port: 5061
resolved_ip: 172.28.1.5
status: active
last_notification: 0
local: 1
}

And after a few seconds only the loca node itself:

kamcmd> dmq.list_nodes
{
host: 172.28.1.5
port: 5061
resolved_ip: 172.28.1.5
status: active
last_notification: 0
local: 1
}

And then again the 3 nodes and the 40.100.109.113 which is a Microsoft IP and I don't know what's doing that IP into my dmq server list.

The DNS record is this:

root@proxy-66f79498cc-b68dd:/# nslookup dmq-proxy-service
Server: 10.96.0.10
Address: 10.96.0.10#53

Non-authoritative answer:
Name: dmq-proxy-service.alex.svc.cluster.local
Address: 172.28.1.7
Name: dmq-proxy-service.alex.svc.cluster.local
Address: 172.28.1.6
Name: dmq-proxy-service.alex.svc.cluster.local
Address: 172.28.1.5
Name: dmq-proxy-service.alex.svc.cluster.local
Address: 172.28.1.4

Any clues why that ip is in the dmq nodes list? And why .7 is missing? Kind regards, -- Aleksandar Sosic mail: alex.sosic@evosip.cloud

Hi,

I have just pushed some changes to master - one of these allows startup

to continue even if initial node resolution fails.

...

There are some other improvements, too, which I have been planning to

push for some time and which should also help in your situation.

...

Can you try again with these changes applied and let me know the outcome?

Cheers,

Charles
