Thank you thank you thank you! Docker processes randomly exiting with "137" suddenly make a lot more sense! 137 - 128 == 9 ... that's SIGKILL, probably via so

Thank you thank you thank you! Docker processes randomly exiting with "137" suddenly make a lot more sense! 137 - 128 == 9 ... that's SIGKILL, probably via some sort of pipe/subshell. We'd figured it was OOM-killer or something similar, but now it seems like there's a bit more of the dots connected between. Who can/will send random `kill -9`s? Probably the kernel, or some sort of supervisory process.
