The majority of you are probably not running on Windows but here is a little PSA. Don't apply bundle patch 10 for 11.2.0.4 on Windows. There is a major memory leak problem with it for the oracle.exe process. See Note 1952786.1. In fact don't apply patch 10 -13 as there is also problems with database links in 11-13. See note 1970666.1 I am waiting to see if patch 14 coming out soon will have the fix for both. I am so frustrated with the lack of support and testing for systems on Windows.
