Recover Standby Database suggests wrong filename

Question

Hi,
I am running Oracle Database 10g Release 10.2.0.3.0 - 64bit Production Standard Edition on Linux version 2.6.9-42.0.8.ELsmp ([email protected]) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3))
I've created a physical standby database, but since I am running Standard Edition, I am not using the DataGuard features. I use the rsync utility to copy over the archivelogs to the standby database, and I apply them periodically to the standby database.
The standby database is started this way :
startup nomount pfile='/u01/oradata/orcl/initorcl.stdby';
alter database mount standby database;
And the archives are applied this way :
recover standby database;
AUTO
(AUTO for the command to apply all available archive logs automatically, using the suggested paths and filenames)
My problem is that once in a while (maybe once every 2-3 weeks), the suggested filename does not have the same format as the rest of the time. I then have to manually specify the correct filename and it goes fine after that.
Example :
In this example, you will see that it is first looking for sequence 22907 (o1_mf_1_22907_5n3m1xrf_.arc), then 22908 (o1_mf_1_22908_5n3m4kf0_.arc) [Notice the format of the file name] and then tries to look for sequence 22909, but looks for filename ".o1_mf_1_22909_5n3md1h5_.arc.qXMz5s"

Can someone explain to me why is this happening please ?
Thanks a lot,

@fjfranken
Yes. If I manually enter the name of the file for the sequence requested instead of passing the suggested fielname, it works fine.
And the log_archive_format is not defined, I am using the flash_recovery_area and let Oracle manage this automatically.
@Hemant K Chitale
Unfortunately, those sequences are not listed anymore in the V$ARCHIVED_LOG view.
Well, I think the the problem might be related to files that are being written to at some time...
Thanks,
Mat
