This looks extremely serious and does not seem to have received any attention so far. The Go issue thread suggests that it's likely related to some kind of socket caching going on in glibc's resolver; if so, this caching should just be disabled completely (replaced with new locally-opened socket per query) unless it can easily be fixed. -- You are receiving this mail because: You are on the CC list for the bug.
