runtime: tests fail with "unexpected signal during runtime execution" when building on solaris #7860
Labels
Comments
Hi, sorry, I missed that comment/mail. This on box of my own, not on Joyents cloud, so if compared to them I guess one difference would be a newer platform image. The zone is a 13.4.1 image with 2GB RAM and no CPU restrictions, single Xeon X3440 on a Supermicro box. I got the same error on an older zone running the 13.1.0 image, but I would anyway guess that if it's something in the OS that differs relevantly that would be the base image. |
For what it's worth, I spun up a zone on another machine. Platform image joyent_20140307T223339Z, base64 13.4.2 zone, 8 GB, Xeon E-1230. Clean install, pkgin in build-essential mercurial, create a user, clone the repo, hg update default (824f981dd4b7) and ./all.bash. On this setup it's not 100% reproducible. If I just run ./all.bash repeatedly I get the above panic about half the time, the other half the test passes. Sorry for the obviously vague info, not sure what more I can provide. :/ |
Please post the output of these commands on the 2GB image:

This is possibly related to issue #7554. It seems to be caused by resource exhaustion, but we haven't yet figured exactly what happens. If you say this this happens in production I will dedicate more time in fixing this. In the meantime, a core dump would be helpful. |

Yes, looks like that could be it - the stack trace is always in GC when the crash happens. It's not "in production" as in any money riding on it, just a personal project that I'd rather run directly on SmartOS than on KVM. How do I create such a core dump (as opposed to the usual stack print)? |
Hm. Sorry, but I can't get that to work. I can get coredumps from non-Go processes by
sending them a SIGABRT (so my coreadm settings etc are OK) but Go binaries don't
generate a core dump even with GOTRACEBACK=crash. I've tried with both this "real" crash
and manually sending SIGABRT and SIGQUIT to no avail.

I'm confused, your paste indicates the existence of a core file.

The corefile that is created is from the regular system /opt/local/bin/sleep just to
make sure the system actually does write core files - it was maybe not the clearest
example in the world to use the same name for my test binary. But panic.go gives me the
same, no "Abort (core dumped)" at the end and no core file. Am I on the wrong Go version?

Please update and try again, specifically check out https://golang.org/cl/97800045/ |
Indeed! Here's a core file and the corresponding runtime.test binary, ran as 'runtime.test -test.short -test.cpu 1,2,4". Attachments:
|
Actually no, sorry, I was too quick there. It does crash, but with "fatal error: runtime: mcall called on m->g0 stack", i.e. issue #6193 but I guess in a new context. |
Ah, glad to hear. I was concerned for a moment. Please post in issue #6193 the stacktrace you get with GOTRACEBACK=2 |
