No output has been received in the last 10m0s, this potentially indicates a
stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on:
https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received
The build has been terminated

There should be a timeout in the python unittest, which would stop the test if
it goes for > 8 minutes, say. It could possibly be in run.py. Or as a wrapper
that is running subprocesses? We don't really know what gets stuck, if it is a
router shutting down, or python client trying to connect somewhere...
> System tests can freeze, observed especially on AArch64 or s390x

> Sometimes the system tests freeze. This is especially frequent on AArch64. It
> is possible this is caused by architecture-specific behavior regarding
> threading. AMD64 is strongly memory consistent, while AArch64 is not. Maybe
> some undefined behavior on AArch64 causes the races to be more serious than
> elsewhere.
