Thanks, Rubeck.
I had seen that bug before posting this, actually. It doesn't quite line up with the issue though, as there is very little load (if any at all) and we are using hardware that isn't on the affected list (fas2240-2). I plan to upgrade the units in any case as we do not want to let this system enter into production with a potential "known-issue" but again, I'm not sure that this is the problem here.
I will report back on this once the update is done though!
