IPython Cluster (SGE) Registration Timeouts about ipyparallel

[jakirkham]

Some logs are placed here ( https://gist.github.com/jakirkham/0ca4ebd38f889628da7f ). To produce, run the following.

ipcluster start --daemon --profile=sge
ipcluster stop --profile=sge

Sorry for not responding in a reasonable amount of time!

I'm going to close this as old and stale, but my hunch based on the logs is that there is a stale ipcontroller-engine.json file not cleaned up from a previous run (note the engine logs loading the connection file before the controller starts, though clock drift can be at play). These files should usually get cleaned up, but if stale files are leftover, an old file could get loaded before the new, valid connection file is put in its place.
