Hi All, We saw an issue with our process running in k8s on ubuntu 18.04. Most of the go routines are stuck for several minutes in http/http2 net code.
Have you seen similar issues ? goroutine 2800143 [select, 324 minutes]: net/http.(*persistConn).readLoop(0xc00187d440) /usr/local/go/src/net/http/transport.go:2032 +0x999 created by net/http.(*Transport).dialConn /usr/local/go/src/net/http/transport.go:1580 +0xb0d goroutine 2738894 [IO wait, 352 minutes]: internal/poll.runtime_pollWait(0x7f5b61b280c0, 0x72, 0xffffffffffffffff) /usr/local/go/src/runtime/netpoll.go:184 +0x55 internal/poll.(*pollDesc).wait(0xc0017e7e18, 0x72, 0x1000, 0x1000, 0xffffffffffffffff) /usr/local/go/src/internal/poll/fd_poll_runtime.go:87 +0x45 internal/poll.(*pollDesc).waitRead(...) /usr/local/go/src/internal/poll/fd_poll_runtime.go:92 internal/poll.(*FD).Read(0xc0017e7e00, 0xc0044a9000, 0x1000, 0x1000, 0x0, 0x0, 0x0) /usr/local/go/src/internal/poll/fd_unix.go:169 +0x1cf net.(*netFD).Read(0xc0017e7e00, 0xc0044a9000, 0x1000, 0x1000, 0xc0026359e8, 0x49d7fd, 0xc0017e7e00) /usr/local/go/src/net/fd_unix.go:202 +0x4f net.(*conn).Read(0xc0000db8b8, 0xc0044a9000, 0x1000, 0x1000, 0x0, 0x0, 0x0) /usr/local/go/src/net/net.go:184 +0x68 net/http.(*connReader).Read(0xc004a4fec0, 0xc0044a9000, 0x1000, 0x1000, 0x0, 0x0, 0x0) /usr/local/go/src/net/http/server.go:785 +0xf4 bufio.(*Reader).fill(0xc003f1a360) /usr/local/go/src/bufio/bufio.go:100 +0x103 bufio.(*Reader).Peek(0xc003f1a360, 0x4, 0x0, 0x0, 0x0, 0x0, 0xc002635ad0) /usr/local/go/src/bufio/bufio.go:138 +0x4f net/http.(*conn).readRequest(0xc0028e1d60, 0x393ed20, 0xc0024e9780, 0x0, 0x0, 0x0) /usr/local/go/src/net/http/server.go:962 +0xb3b net/http.(*conn).serve(0xc0028e1d60, 0x393ed20, 0xc0024e9780) /usr/local/go/src/net/http/server.go:1817 +0x6d4 created by net/http.(*Server).Serve /usr/local/go/src/net/http/server.go:2928 +0x384 Is there a know issue or something obvious from the backtrace here. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
