SAP S/4HANA Error 657: SQL Task Cancellation Timeout
Description
This error indicates that an attempt to cancel an ongoing SQL task in SAP S/4HANA failed because the task did not respond to the cancellation request within the allotted timeout period. It typically occurs when a long-running or resource-intensive database operation becomes unresponsive, preventing a graceful shutdown.
Error Message
ERR_SQL_CANCEL_TASK_TIMEOUT_REACHED
Known Causes
4 known causesDatabase Overload or Deadlock
The underlying database server is experiencing high load, resource exhaustion, or a deadlock, preventing it from processing the SQL task cancellation request promptly.
Inefficient SQL Query Execution
The SQL task itself is excessively complex or processing a vast amount of data, making it too slow to acknowledge and respond to a cancellation signal within the timeout.
Network Connectivity Issues
Unstable or high-latency network connections between the SAP application server and the database server can cause the cancellation request or response to time out.
Resource Contention
The task may be blocked waiting for a locked database resource, rendering it unresponsive to external cancellation commands until the resource is released.
