warm standby question

Hi,

I have a primary server (9.1), which does wal archiving like this:

wal_level = hot_standby
archive_mode = on
archive_command = 'test ! -f /home/autobackup/wal/%f && cp %p /home/autobackup/wal/%f'


then I have a warm standby with this configuration in recovery.conf:

restore_command = 'cp /opt/WAL/%f %p'
standby_mode = on



when I then start the server it applies all WAL files. But when I then stop the server after a few minutes and start it
again,it asks for a WAL file it already processed. 

Logfile:
