> As of yesterday we started to experience issues with Travis Builds. It seems that the
machines that are used for our builds suddenly get very resource-strapped (memory and CPU).
> We have started to experience Memory issues:
> https://travis-ci.org/apache/airflow/jobs/562395978
> ```
> OSError: [Errno 12] Cannot allocate memory
> OSError: [Errno 12] Cannot allocate memory
> ```
> And Lack of CPU:
> https://travis-ci.org/apache/airflow/jobs/562425370
> ```
> error execution phase preflight: [preflight] Some fatal errors occurred:
> 	[ERROR NumCPU]: the number of available CPUs 1 is less than the required 2
> ```
> We had recently changed CI build infrastructure to use different approach for Docker
images, so we thought this is a problem with the new CI system, however reverting the changes
does not help - I run it on my own Travis fork and got the very same problems - memory and
CPU issues:
> https://travis-ci.org/potiuk/airflow/builds/562430507
> I opened a community question for that: https://travis-ci.community/t/builds-often-fail-because-of-lack-of-resources-memory-cpu/4331
- that's all I can do.
> Can you please escalate with Travis support whether they changed something  in the machine
configuration (it looks like they did).
