Proc does not seem to work correctly

[tobiasfrejo]

Using discosat/CSH to connect to the application and send proc commands fail.

Running CSH and csp-pi-gpio on same host with zmqproxy. ordinary param commands does work as expected, so there is a working connection between the nodes.

> proc new
Created new procedure
> proc noop
Added noop instruction to procedure
> proc push 42 12
Failed to push procedure to slot 42 on node 12 with return code -1
