| Description |
|
While Carbon takes less than a second [0], Nitrogen frequently takes more than 10 seconds [1] to accept a connection, causing test failures. Karaf.log [2] shows the pause happens after "Generating host key" at 19:57:39,100.

Yeah, this seems like performance regression in setting up SSH connection to NETCONF northbound servers in some cases. This was possibly introduced by bumping crypto libraries to newer versions or tweaking some crypto settings. Updating NETCONF user guide with this regression: This causes the large part of NETCONF MDSAL suite to be unusable, since setting up the SSH connection to MDSAL northbound is its first step. Increasing timeout to 60 seconds so the suite can connect to MDSAL northbound and perform its other tests. |

The loop-back connection is no longer used and this only happens on first startup. |
