19.1 rc2 and igmpproxy - 10 sec. freeze every 30 minutes on IPTV

[jpatriarca]

Hi team,

I've detected that after upgrading from 18.7.10 to 19.1 (rc1 and rc2) my IPTV service freezes for 10 seconds every 30 minutes. After some further investigation I've detected that after the rc.newwanip and rc.newwanipv6 scripts runs on the WAN interface, 1 second after igmpproxy services goes down and restore itself. Since that it runs in sequence, there are two igmpproxy service stops, as the following logs indicates (full activity in system.log related to the issue:

Tried to disable DDNS service since that was my first assumption on the error but with no results.

WAN interfaces are both configured for DHCP/DHCP6.

Require your help and knowledge about this to solve this problem when possible. Let me know if you needfurther debug, logs or commands to be executed.

PS - I remember on a equivalent error in OpenWRT and igmpproxy also related with this automatic script a couple of years ago. If it helps...

Hi all,
Just an update to inform that this situation still happens in 19.1 release and 19.1.1 upgrade.

There's anyone that could help on this to try to resolve this issue?

Thank you

Not sure but could be related to this issue...
https://forum.opnsense.org/index.php?topic=11456.30

particularly this part...
"Firewall: Settings: Advanced: Dynamic state reset" active (Reset all states when a dynamic IP address changes.This option flushes the entire state table on IPv4 address changes in dynamic setups to e.g. allow VoIP servers to re-register.)

The same ticket was raised on GitHub, sadly no link between forum and it in any direction. I noted the same thing there:
