1435900 - `./mach build` fails to build esr52 - the resource monitor seems broken

Status: RESOLVED DUPLICATE of bug 1384062

(Firefox Build System :: General, defect, P1)

Description

[Dana Keeler (she/her) (use needinfo) [:keeler]]

This is preventing me from fixing bug 1435644 and reopening the esr52 tree.

Error running mach:

    ['build']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

AssertionError

  File "/home/keeler/mozilla-unified/python/mozbuild/mozbuild/mach_commands.py", line 459, in build
    monitor.finish(record_usage=status==0)

Just ignore the error. It happens at the *end* of the build.
