Issue is resolved.
Problem was with Q7 restart handling.
In one core system, terminate event will occur a little bit later then restart is happen.
On restart original launch instance was terminated and removed from our internal AUT map. But it still was contain Q7_LAUNCH_ID, so then terminate event was received launch was incorrectly associated to new launch and terminated.
Q7 server is not expected such situations, so have both fixes in Q7 and Q7 Cloud.
Fill resolve issue then new Q7 Cloud instance will be uploaded.
