During rebalance seeing multiple erl_crashes due to "application_start_failure,ns_ssl_proxy,{shutdown,{ns_ssl_proxy,start,[normal"

Run test using test runner on
python testrunner -i ~/here.ini -t rebalance.rebalancein.RebalanceInTests.rebalance_in_with_ops,nodes_in=3,items=0,default_bucket=false,standard_buckets=5,sasl_buckets=5

0.
1. On a single node, create 5 standard buckets(ports 11214 through 11218) and 5 sasl buckets
2. Add 3 nodes and rebalance in
3. For each standard bucket, we see a lot of erlang crashes , attaching the erl_crash dump on the bug.

Port server xdcr_proxy on node 'babysitter_of_ns_1@127.0.0.1' exited with status 1. Restarting. Messages: {"Kernel pid terminated",application_controller,"{application_start_failure,ns_ssl_proxy,{shutdown,

{ns_ssl_proxy,start,[normal,[]]}}}"}

Crash dump was written to: erl_crash.dump.1390600582.2413
Kernel pid terminated (application_controller) ({application_start_failure,ns_ssl_proxy,{shutdown,{ns_ssl_proxy,start,[normal,[]]}

}})

• The rebalance slows down but succeeds for the buckets.
• This test which ran clean until 2.5.0-1058 , fails with timeouts Jenkins from build 3.0.0-310 onwards.

Attaching logs.
