Thanks, looks like my initial suspicion was off.

If you feel brave enough, you can take a coredump of one of the
said workers with "gcore", load it to gdb (together with appropriate
debug symbols) and from here, you can investigate further.

I have no first-hand experience with debugging Ruby interpreter,
lest the interpreted script's code should be of interest,  but this
looks promising: https://gist.github.com/csfrancis/11376304

Hope this helps.
