IBM is advising all clients to download and apply this iFix as soon as practical. It is a single-defect iFix that is isolated to correct a defect in a single component of RAD that communicates errors to the support service. If unfixed, this condition can cause serious performance problems for the users of RAD, or potential network problems for your company's infrastructure. Applying this critical fix as soon as possible is highly recommended to ensure continued stability.
The iFix is available directly from IBM Installation Manager (IIM) within the product, or downloadable directly from IBM FixCentral. The locations are documented in the Flash published today: http://www.ibm.com/support/docview.wss?uid=swg21573964
