Looks like the INJ_TRANS node had a failed injection last night, and it has been stuck in the FAILED_DURING_ACTIVE_INJECT state since. I don't see anywhere in the code a way for it to get out of this state without going to either manual, or INJECT_KILL first. So I brought it to INJECT_KILL and then back to INJECT_SUCCESS.

Log for INJ_TRANS during failed injection is attached.
