I decided to give the latest obelisk a try on ubuntu with offline usage.
It works already partially.

Starting from a normal setup with network - everything works fine.

Turning off networking.
# service networking stop

Start worker
ubuntu@bitcoin:~/worker1$ obworker
Using config file: /etc/obelisk/worker.cfg
Press CTRL-C to shut down.
DEBUG [worker]: Listening: tcp://*:9091
INFO [worker]: worker ready
DEBUG [worker]: Heartbeat: tcp://*:9092
ERROR [protocol]: Failed to start handshake service: Bad stream
Node started.

Then send a request
ubuntu@bitcoin:~/worker1$ sx fetch-last-height
291345

great! it works!

Then a second request
ubuntu@bitcoin:~/worker1$ sx fetch-last-height
oh ...

I get:

obworker: worker/worker.cpp:29: void
obelisk::send_worker::queue_send(const obelisk::outgoing_message&):
Assertion `socket.self()' failed.
Aborted (core dumped)

I use the master HEAD.
This behavior is repeatable.

Quick fix?
