Implications of increasing net.ipv4.igmp_max_memberships

Solution Verified - Updated -


  • One of our developers asked us to up net.ipv4.igmp_max_memberships from the default of 20 to 30.
  • It looks like we'd be holding onto that rtnl_lock() for a little bit longer, but I doubt that we would really see any impact from that.
