Description
The relevant error message in the logs (running at *=20)
*** Processing command 70=CMD_READ from socket 10
_gdp_req_dispatch >>> CMD_READ (70) [gcl->refcnt 1]

Trying Zeroconf:
Followed by this, the log-server just starts looking for zeroconf. I am not sure if the 'signature write failure: Success' message is related to the lost connection, or if it is a separate issue. See attached log for one full run of gdplogd.

Just a hunch, but I wonder if this might be related to Issue #9 (Router terminating connections abruptly). I say this because the EOF indicates that the connection was closed. If so, this may be a way to trigger that bug, but not be a bug itself.

The Zeroconf part of this is resolved (see issue #30). The signature write failure part is still open.

Here's how to reproduce this:
- Start
gdplogd. - Use the visualization tool at http://gdp.cs.berkeley.edu:8888/ and go to Chair 1,
- Hit 'Plot'.
- Look at the system log of
gdplogd. It should be something like:
get_open_handle: opening OSbcXbklH_LEH2qqdo_PiiohaEAKJlf6fx6MQBuO934 _gdp_pdu_out: signature write failure: Success _gdp_event_cb: got EOF, 0 bytes left Trying Zeroconf:
The log OSbcXbklH_LEH2qqdo_PiiohaEAKJlf6fx6MQBuO934 maps to edu.berkeley.eecs.swarmlab.device.c098e530002b, which exists but is empty.
