Just upgraded 5 servers from 11.2 to 11.2.1. 3 of the 5 upgraded fine and rebuilt deployment packages with no errors. The other 2 servers failed the "rebuilding deployment packages" process. Looking in the loader messages log file I am seeing a java IOException when trying to rename one of the package files. When looking at the folder and file listed in the error line, it looks as though the original file is there as well as a new file with a newer version tied to the name. Not sure if this was something I needed to worry about as I am planning on updating to 11.2.1 MU2 as soon as possible to test some fixes that development did for me to address an issue with Locations. Any ideas?
