OK, here's the time index at which it b0rked:
18:28:38 sum 1106.00
18:28:39 sum 1037.62
18:28:40 sum 1069.00
18:28:41 sum 1167.00
18:28:42 sum 1155.00
18:28:43 sum 1339.00
18:28:44 sum 18355.00
18:28:45 sum 17845.45
18:28:46 sum 15285.00
18:28:47 sum 17511.00
18:28:48 sum 17568.69
18:28:49 sum 17704.04
18:28:50 sum 18566.67
18:28:51 sum 18913.13
And the entire log of the minute 18:28 is here:
