mongorestore random crash (fatal error)

问题

I'm on macOS 10.12.

mongod --version
db version v3.2.8
git version: ed70e33130c977bda0024c125b56d159573dbaf0
OpenSSL version: OpenSSL 1.0.2h  3 May 2016
allocator: system
modules: none
build environment:
    distarch: x86_64
    target_arch: x86_64

When I use a mongorestore:

mongorestore --drop --db mydatabase /path/to/mongodump

The import starts but it crashes 90% of time:

fatal error: unexpected signal during runtime execution

... (real log is very long)

Is it specific to my OS ?

Thanks.

回答1:

I can confirm that it is definitely something with the OS as I have updated and am running into this same exact issue as well. I am currently digging into it, if I find anything I will let you know!

UPDATE:

After doing some investigating it seems that it has to do with the Go dependency that MongoDB uses. Currently MongoDB is using v1.4.2. Turns out that there are problems with older versions of Go on macOS Sierra. https://github.com/golang/go/issues/16570 explains that the issue is resolved with v1.7. Unless there is a way that you can have MongoDB point to Go v1.7 I am not sure if this will be resolved until MongoDB upgrades their dependencies.

UPDATE 2: I was planning to file a bug with MongoDB relating to the issue until I stumbled onto this... https://jira.mongodb.org/browse/TOOLS-1450. It seems that MongoDB 3.2.10 will use Go v1.7 and should fix the issues that you and I are seeing.
