Yeah, that seems excessive. FWIW, the most recent upload didn't change
anything related to the build options, so this has built successfully in
the past.
It built successfully on armel with the auto-detected value -j4, so it's
surprising to see it pick 64 if there are only 2 processors. The only
reference to the number of compile threads is this bit of Groovy from
build.gradle:
defineProperty("NUM_COMPILE_THREADS",
"${Runtime.runtime.availableProcessors()}")
I will have a look to try to determine where the value of 64 is coming
from. We can clamp the value if need be.
Cheers,
