IGMP proxy keeps crashing

[babipanghang]

Good afternoon,

I've set up IGMP proxy for use with IPTV. It is configured with an upstream to VLAN 640 on the WAN side with a couple of subnets (dutch T-mobile Thuis IPTV) and a downstream interface set to match my LAN subnet.

When we are using IPTV (working fine by the way), IGMP proxy will crash within 5 minutes or so and IPTV will be interrupted, after which i can restart the IGMP proxy service and it will continue for another 5 minutes.

Under system logs -> Routing it does log the following when crashing:
Aug 24 19:14:45 igmpproxy 80480 select() failure; Errno(4): Interrupted system call
Aug 24 19:19:18 igmpproxy 86544 select() failure; Errno(4): Interrupted system call

Hope to get some hints here to debug this. It's my first pfSense box, please bare with me.

Thanks!
