Agreed. I think there is a deep problem, but the deep problem is here rather than in the Go tests. thanks Dan On Mon, 2017-10-02 at 18:16 -0700, Ian Lance Taylor wrote: > 10 minutes is the default timeout, so that's why that run failed. > > 5 minutes, the time shown above, is an extraordinarily

Trying today, the roles of the machines have reversed; the one failing on Friday passed today and vice versa. The passing test: ``` $ time go test -test.short cmd/go ok  cmd/go 339.070s real5m45.804s user1m38.821s sys 0m49.390s ``` The version is a lie - there is a change to mal

I have just tried replicating the issue today and this time, one machine passes everything, while the other does not. I am beginning to suspect that file system loads may be a possible cause (the head node is quiet, but the file system is shared across many nodes in both cases). The newer machine

I can replicate this on another newer RHEL machine. In both cases the machines are quiet (they are the head nodes of HPC infrastructure and don't see a great deal of work due to the HPC use policy. I have tried building previous versions and see similar though different failures going back to 1.7

I am seeing all.bash fail when testing cmd/go with a likely cause being internal/poll.runtime_pollWait. I'm trying to build go1.9 (with a change to the heap size), but all.bash fails as shown below. Is this a known problem? and if it is, is there a workaround. thanks ``` panic: test timed out af
