[os-igmp-proxy] Restarts every 30 minutes after c.newwanip and rc.newwanipv6 scripts execution

[jpatriarca]

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...

This behaviour occured in 19.1 RC version, 19.1 release and now on 19.1.1 release. Will someone look on this topic or your solution will be to revert to 18.7 version?

Sounds like opnsense/core#3197 -- if you agree, please close this one.

[jpatriarca]

Thanks for the feedback. You're right, the bug seems the same as the one you've refered. Will process to close this one. Thank you
