[ee4j-build] Unexpected Jenkins failure with "git checkout" returning st

[Scott Marlow <smarlow@xxxxxxxxxx>]

Hi,

Any insight as to what this failure [1] represents and how to resolve?
 The command being executed is "git checkout -f
c457c40af61d307b0dea0e0489fed7ab4c3e8490" and the exit code is 137,
which could mean a memory allocation issue (from googling for that
exit code) but I'm not sure.  Have other seen this on our Jenkins and
solved it?
