Auditbeat 7.8.0 socket only send data in 2 minutes

Hi all,

I have something weird since upgrade to 7.8 of auditbeat, below the log that produce by auditbeat
I use Centos 7.6 with kernel
Linux sync-02 3.10.0-1062.18.1.el7.x86_64 #1 SMP Tue Mar 17 23:49:17 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

My config of auditbeat like below for auditbeat.yml

My ipv6 disabled by network-scripts startup

PEERDNS="yes"
PEERROUTES="yes"

My problem is the socket event don't send the event 2 minutes after auditbeat start and the result in auditbeat index for event.category: network_traffic is just 2 minutes range then empty. If i restart the auditbeat, the socket event send again, only 2 minutes then disappeared.

Below the result of the auditbeat log.

In other node, with kernel
Linux asdpsync 3.10.0-957.10.1.el7.x86_64 #1 SMP Mon Mar 18 15:06:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
and use auditbeat 7.7.1, there's no issue at all, using standard installation and configuration.

I already downgrade to 7.7.1 for the problem node, but no luck. Upgrade again to 7.8.0 also still have this problem.

Is there any workaround to make the socket event stream come back again?

Regards,
Fadjar Tandabawana

Do I need put into bug report?

Please advice...

Regards,
Fadjar Tandabawana

Just report what I've done...
Downgrade the auditbeat into version 7.6.2 and the socket event come back again and stable.
