It seems that this is from /etc/cron.d/mdadm having a checkarray command which runs on the 3rd of the month, my slowest server didn't complete that in a reasonable amount of time while the other servers which aren't disk IO bound completed it before I noticed.
I'd have thought that was obvious from the emails cron sends about it. Hmm, on second thought maybe the emails I remember come via logcheck.
