While reading a checkpointed spill file, PowerExchange encountered an error during an I/O operation. This message provides diagnostic information about the error.
If checkpoint exceptions are tolerated, the state will be restored from the checkpoint. However, data loss will occur. If checkpoint exceptions are not tolerated, processing terminates.
Examine the error text to determine the root cause. If the cause is corruption of the checkpoint data, you must either delete the checkpoint or set the EXCEPTIONS=TOLERATE parameter in the CHECKPOINT statement to tolerate the error and enable processing to continue.
