Hello, We had a strange problem using lksctp-tool where checksctp would hang there on some of our machines and process cannot be killed anyway (with status d/d+). After some investigation, we found out that whether ipv6 is enabled could impact the behavior of the library. So, my question is that, is this a requirement by design or it just happens to occur that ipv6 is required? Any suggestion to bypass this (not to rely on ipv6) would be appreciated very much.
