Archive Log Creation Creating Trace File

[lesstjm]

I have a 9.2.0.3 database on Solaris and I noticed that everytime an archive log is created it is creating a trace file in my bdump directory just saying that the logs were created. Why does it do that?

and the contents are?

This is the contents of one of the files. I have changed the name of the database:
