slapd_db_archive log rotation

Hi there.

I'm using slapd_db_archive with the -a flag to identify BDB logs which can be safely deleted.

I've recently noticed my logs are building up and -a does not produce any output.

However the -l flag does successfully list the log files.

Therefore any use of the -d flag to remove them does nothing.

I'm almost certain these old logs are not being used (there's about 20 going back for several months now) but still slapd_db_archive does not pick up on them.

Can anyone advise what may be happening here or how I can debug this further ?

Thanks very much.
