Well, I tried it only on the playgound because it seems to reproduce the bug there, so I didn't bother to try on my machine. Now I tried and indeed it runs fine for me too (linux 4.15.0 - go 1.18). BTW even if the trimmed-down example seems to work fine (at least outside of the playground) I still see the bug in my full project, it is composed of many pieces that needs to run together to actually reproduce it, it's a bit hard to post here. :-( I tried to pprof the application, and this is the state when it locks https://pastebin.com/raw/L1wa5hz6 basically everything is waiting on mutex, except the last goroutine that is trying to do a unix.Close(..) (and it is supposed to unlock everything else when done, but it's blocked for some reason an it never returns). syscall.Syscall+0x4 go1.18/src/syscall/asm_linux_amd64.s:20 /sys/unix.Close+0x2f go/pkg/mod/golang.org/x/sys@v0.0.0-20220405052023-b1e9470b6e64/unix/zsyscall_linux.go:571 this is the version of x/sys: golang.org/x/sys v0.0.0-20220405052023-b1e9470b6e64 // indirect C -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
