  #1楼 @blov 现在的感觉是在调度器部分死锁了 gdb进去调试 ``` (gdb) bt #0 runtime.futex () at /home/xuegeng/go/src/runtime/sys_linux_amd64.s:307 #1 0x000000000042c4e0 in runtime.futexsleep (addr=0x11d3020 <runtime.sched+192>, val=0, ns=100000) at /home/xuegeng/go/src/runtime/os1_linux.go:57 #2 0x000000000041103b in runtime.notetsleep_internal (n=0x11d3020 <runtime.sched+192>, ns=100000, ~r2=false) at /home/xuegeng/go/src/runtime/lock_futex.go:174 #3 0x000000000041112b in runtime.notetsleep (n=0x11d3020 <runtime.sched+192>, ns=100000, ~r2=false) at /home/xuegeng/go/src/runtime/lock_futex.go:194 #4 0x00000000004334ad in runtime.stopTheWorldWithSema () at /home/xuegeng/go/src/runtime/proc.go:963 #5 0x000000000045f419 in runtime.systemstack () at /home/xuegeng/go/src/runtime/asm_amd64.s:291 #6 0x0000000000433870 in runtime.startTheWorldWithSema () at /home/xuegeng/go/src/runtime/proc.go:986 #7 0x000000c82001a000 in ??

() ``` 然后strace 时 显示这样 目前GO 版本是1.6 ,debian ``` [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) [pid 231942] futex(0x11d3020, FUTEX_WAIT, 0, {0, 100000}) = -1 ETIMEDOUT (Connection timed out) ``` 我试试gops ，感觉是不行的。。
