Internet search says "python Memory Error" probably means running out of address space,
such as on a 32-bit armv7hl. What uses lots of address space? Could there be
too much contention from other jobs on the machine? Paging space (swap space)
is a "temporary" constraint on address space of every running processes
The armv7 builders are virtual machines with 24 GB of ram per system. I believe that there is only 1 build per builder at a time so this build is going to contend with itself. However, I believe any process is going to be limited to something under 4GB (3.6?) so that is going to be the 'first' thing to look at. The next thing would be to look to see if there are 'hardware' errors on the guest.
And yes.. yes there are:

will work with release engineering to see if they can take this builder out and reboot it.

That's a bug in the exception handler.
