Interesting.. it might be related to this commit and we're trying to 
reproduce it.

Did you try to remove that code and run again? does it work without the 
additional of zombieReaper?
does the connectivity to the storage work well? when you run 'ls' on the 
mounted folder you get see the files without a long delay ? it might 
related to too long timeout when validating access to this mount..
we work on that.. any additional info can help

Thanks.

it happens only when you call to getCapabilities.. so it doesn't related 
to the flow, and it can't effect the storage.
