Thanks for replying.
But I could't find relation between the RequestXLogSwitch function and the error I met.
For perfromance purpose , I change the pg_start_backup checkpoint type from CHECKPOINT_WAIT to CHECKPOINT_IMMEDIATE,
doesit matter?

I believe there's a related bug fix in 8.3.8.
BTW, -hackers is not the place for this type of question.
