Thanks for getting back to me, I've just checked each of those files you suggested, and everthing looks fine in terms of config. Just a quick question, I realised I had mover set to run at 11:00 and increment pause time also at 11:00, with "Pause array operations while mover running" also set to "Yes". Could that have caused my issue? with maybe the Pause array operations getting in first, pausing the parity check at 11:00 before the pause cron ran, and then restarting at 11:06 not knowing it should be in a paused state? I run a partiy check every 3 months, so I'll set myself a reminder to turn on test logging and see if it occurs next time. I've been using the plugin for a while, and this is the first time I've ever had the issue, so hopefully it was just a one off.
