 When uploading files to the volunteer grid on I2P, I received the
 following exception:

 I do not see any flog files from the time of the error (and it took place
 when I was AFK).

 At http://127.0.0.1:3456/status/ it's still visible in the "Active
 Operations" section, even though the event took place hours ago.

 For what it's worth, there are other failed upload attempts that are
 remaining in the list of "Active Operations" (even though they failed
 many, many hours ago). I'm retrying the batch upload; I'll try to generate
 the flog files if it errors out while near.

 (The fact that uploads may fail occasionally on networks like I2P or Tor
 isn't unusual; that they're still shown as active long after failing is
 (and it's not something that I saw with 1.8.x)).
