Re: ConnectionException in container, happens only sometimes
Here are logs of RM and 2 NMs:

RM (master-host): http://pastebin.com/q4qJP8Ld
NM where AM ran (slave-1-host): http://pastebin.com/vSsz7mjG
NM where slave container ran (slave-2-host): http://pastebin.com/NMFi6gRp

The only related error I've found in them is the following (from RM logs):

Though from stack trace it's hard to tell where this error came from.

Let me know if you need any more information.
