Delete these files manually or use some job to clean up diskspace.


To prevent the issue,
1. Apply interim Patch 4591936 on top of 10.2.0.3 according to the readme.
Please note that these one-off patches are not regression tested and hence you are advised to apply the same on a test server before applying it on a production box.
