Hi Charitha, When an operation response get stored DM_ENROLMENT_OP_MAPPING table gets an "update" while DM_DEVICE_OPERATION_RESPONSE gets an "insert" from the response data. AFAIK when an update happens it will lock the table, depending on the transactions handling [1 - Transaction Isolation] of H2 database. And if there is a response burst, this error could happen. I think H2 database may not be able to handle the load.
