CMB long pool question

[adamdembek]

We are testing cmb-2.2.46 in Kubernetes environment.

We started two cmb containers and Kubernetes balance the traffic to those containers from our application.

Our FE application sends receiveMessage with WaitTimeSeconds 20 to one of the CMB

this.sqs.receiveMessage({
"QueueUrl": this.queueUrl,
"MaxNumberOfMessages": this.maxNumberOfMessages,
"VisibilityTimeout": 30,
"WaitTimeSeconds": 20 }

I see that when another application send something to this queue through second cmb container the FE receiveMessage still waits until WaitTimeSeconds.

I see that cmb-xm2el that got the SendMessage request tries to send longpoll_notification_sent to cmb-6a2ad (172.10.71.7)

But logs in cmb-6a2ad do not show anything until the timeout.

The telnet 172.10.71.7 5555 between two containers is working.

What else can be wrong in our configuration that cmb-6a2ad did not receive longpoll_notification_sent ?

In properties we have

cmb.cqs.longpoll.enable=true
cmb.cqs.longpoll.port=5555
