Continuous recovery stopping

Hi all

I have a hot standby replication setup.
But for no apparent reason, it stops the recovery. Here is a part of the
log:

2011-02-21 11:07:03 BRT LOG: restored log file

D:/Archive/026/failover.trigger": return code 1
2011-02-21 11:18:05 BRT LOG: database system is ready to accept connections

And here is my recovery.conf file:

restore_command = '"C:/program files
(x86)/postgresql/9.0/bin/pg_standby.exe" -s 30 -t
D:/Archive/026/failover.trigger D:/archive/026 %f %p %r
2>>D:/archive/026/pg_standby.log'
trigger_file = 'D:/Archive/026/failover.trigger'
recovery_end_command = 'del D:/Archive/026/failover.trigger'

What can be making it stop the recovery. Any ideas?

Thanks
