That is an Ext.js error that means a polling request is timing out, but the SHARE-side log you've posted seems to indicate that the query finished successfully (although couldn't find any matching services, so it wouldn't have returned any answers…) Can you try your query with the command-line client (
https://code.google.com/p/sadi/wiki/SHAREClient)?
I can't attempt to reproduce your error myself and obtain a more detailed log that might indicate what's wrong because I don't have the query you used (the link you've give that seems like it should provide it doesn't work; i.e.:
https://code.google.com/p/bionlp-sadi/w/lis). Also, if you've got a custom registry setup, I'll need that, too, so that I can access the same services you are using.
Cheers,
