When the stone is started with the new executables during upgrade, the Stone attempts to start the Reclaim and Admin GcGem. These gems are not yet able to login due to the version mismatch. The Stone did not reattempt to start the GcGems later.
After upgrade is complete, shut down and restart the Stone. You may also explicitly restart the GcGems using System startAllGcGems.
