The listener works but the sender does not. I have alre= ady tried using SO_REUSEPORT instead of SO_REUSEADDR and this makes no differen= ce to any other platform I am testing from working. I dug around the current open issues to see if there was something relevant, and I think this might be exactly the same issue. This is a different langu= age and potentially does share C library accesses in common with the Perl probl= ems being reported here. I hope my report can add something towards solving this issue. I am at least relieved to see that this looks like a FreeBSD kernel bug sin= ce as I said, the same code above also works on MacOS. However, the *bsd platf= orms on the Go standard library are the least exercised of all the major platform ports and it's possible that even though it looks like a similar bug it may= not be. --=20 You are receiving this mail because: You are the assignee for the bug.=
