Yesterday there were no leases in the kea-leases4.csv file (only headers), this morning there are a handful, and their expiry times are for tomorrow - which would be correct if they just renewed or acquired them. Their corresponding lease entries in kea-leases4.csv.2
are expired as of this morning, except one that expires in about three hours. Mac addresses and all other info is consistent across files (aside from expiry epoch).<br>
<br>
On a related note: I've no idea how the 2<sup>nd</sup> file even gets created. While testing, before rolling out to production, I'd noticed this and deleted the "csv.2" versions, but they always come back.</div>
