Ack. This works.

Your log:

Explain, to yourself not to me, those anomalies:

"1117524058.DEBUG 1117524063:".....

Why this strange formatted line, where does "1117524058." come from.
Is your first intended update indeed at time 1117524063 ?
I guess so, as it's five seconds.  In that case the log could
use a carriage return/newline pair.

"DEBUG 1117524151:21.6902927580894:15.5:38:2:144990:2:0:0
.DEBUG 1117524151:30.50".....

Why a dot, why that second timestamp 1117524151

Of course you get an error if you update twice at the same time.
This is expected behaviour.  Did you notice this?
