IGMP Snooping reliability

Hello, is somebody using IGMP Snooping with HW Offloading on CRS? What are your experiences? Is it working well, is it reliable?

I am a little conservative in production environment, still using 6.40.8 bugfix, but there are some places I started to test current branch with this new function. Unfortunately, I have very bad experiences - CRS112-8G-4S is rebooting each 2 minutes with IGMP Snooping. CRS109-8G-1S-2HnD is working, but there are some random troubles after I turned that function on, some packet losses, I have spent few hours until I found that turning off IGMP Snooping will solve the troubles. I am using 6.42.2 and of course many VLANs.

my rb3011 seems to freeze each time I activate or deactivate it. Winbox & console almost unusable. All interfaces gone, but I can connect to the box.

After I reboot the box it seems to work.
On 6.42.2

Seems still buggy to me.
