If you are using the configuration option allrows_dss when upgrading from a 15.0.x version to 15.0.2 in parallel mode, the server may stack trace when the optimizer selects a plan that requires tempdb, which has not yet been onlined.
Workaround: Change configuration from allrows_dss when rebooting with the new binary. After minor upgrade is complete the server can be returned to its previous configuration.
