My guess is that <something> happened to prevent packets being
received. So renewal at 10:14 went OK, but renewal at 10:19 (50% of
lease used) failed. Since you say you didn't touch it, I guess you've
no idea if any other network traffic was working.
At 10:22, about 75% of lease used, the client starts to renew more
vigorously. Finally, at 10:24:46 (7 seconds before lease expires),
the client gives up and broadcasts a Discover. At this point, the
<something> that broke the network got fixed (by the act of the DHCP
client configuring the interface ?) and the client then continued
normally.
As to what the <something> is, no ideas !
