AppVeyor spuriously killing a dist- job with message "Build exceeded allowed resource quotas"

[pnkfelix]

Symptom: A job on AppVeyor (currently all are dist-x86_64-mingw) is killed while creating the setup EXE, with the AppVeyor message

Build exceeded allowed resource quotas. Fix your build to consume less resources or contact AppVeyor support to request quotas increase.

We guess the quota mentioned is the disk space.

#57514 (comment) (2019-01-30T21:04:02Z) is the first known instance. This error is occurring once to twice per day.

#57514 passed after retry.

When comparing logs:

• failure: https://ci.appveyor.com/project/rust-lang/rust/builds/22006972/job/7ooc207am74l0w8p
• success: https://ci.appveyor.com/project/rust-lang/rust/builds/22023180/job/rj0c96ymab0thxk2

Both get to the point:

Successful compile (288.031 sec). Resulting Setup program filename is:
C:\projects\rust\build\tmp\dist\exe\rust-nightly-x86_64-pc-windows-gnu.exe
rust.wxs
ui.wxs
rustwelcomedlg.wxs
RustcGroup.wxs
DocsGroup.wxs
CargoGroup.wxs
StdGroup.wxs
ClippyGroup.wxs
MiriGroup.wxs
AnalysisGroup.wxs
GccGroup.wxs

Then failed job output stops (process hangs?) while successful job prints warnings for .wsx objects and finishes the build.

EDIT: Also taking back my words:

Somehow build succeed but AppVeyor detected it as a fail:

Builds seems to freeze.

I've replaced the issue description and title with the actual problem.

Contacted AppVeyor support about this.

According to AppVeyor support the problem was disk space, and they increased our quota by 10Gb. Closing this.
