A successful task mgmt command is logging errors, making it look like problems were encountered. This is due to log messages for the device/target and bus reset handlers having the LOG_TRACE_EVENT flag set. Fix by adjusting the event flag such that the call to the logging routine only receives a LOG_TRACE_EVENT if a prior call actually failed.
