CAUSE

This is due to Bug:18766012

SOLUTION

There are two Options to get rid of this Problem:

1. Ignore those Traces and create an OS-Job to regularly delete those Tracesfiles
2. Apply Patch 18766012 for your Platform on Top of 11.2.0.4 at least on the Standby Database.

Note that this Bug is fixed in 12.x, too.
