Zameer Manji commented on AURORA-1021:
--------------------------------------
[~StephanErb]: If the user specifies a very small value (say 1MB) and we create
a container with 1MB of RAM, it is possible for the container to OOM when the
executor is creating the sandbox. This results in no sandbox created and can
make this issue difficult to debug. This is here to ensure that the smallest
container created by Aurora doesn't have the executor OOM right away. This
ensures the sandbox is created and the user can look at their application logs
and make the decision to resize the container.
> Increase MIN_THERMOS_RESOURCES to prevent thermos OOMs.

> Priority: Minor

> After doing some experiments that involved reducing the executor overhead to
> 0 I noticed the peak executor memory usage is greater than 128MB. This causes
> OOMs when the container starts even for very small tasks. To prevent this the
> memory portion of MIN_THERMOS_RESORUCES should be increased to 256MB.
