postmaster problem

Hi friends,

I run cygwin under win2000, and when I want to connect
to the postgreSQL, I meet the problem as following:

$ pg_ctl -D /usr/local/pgsql/data/ start
postmaster successfully started

$ DEBUG: database system shutdown was interrupted at
2002-12-06 16:14:45
DEBUG: CheckPoint record at (0, 2144336)
DEBUG: Redo record at (0, 2144336); Undo record at

DEBUG: NextTransactionId: 1505; NextOid: 51488

DEBUG: redo starts at (0, 2144400)
DEBUG: ReadRecord: record with zero len at (0,

DEBUG: redo done at (0, 2238464)
FATAL 2: XLogFlush: request is not satisfied
/usr/bin/postmaster: Startup proc 1432 exited with
status 512 - abort

At the same time, the postmaster.pid file can not be
produced again.

Thanks in advance

Leon
