Red Alert : Media Manager Errors

About a month ago I signaled a Red Alert and how you can subscribe to the 'Red Alerts Subscription Service'. Well, today there's another one for 'Media Manager Errors in z/OS 1.6, 1.7 and 1.8'. Here's a little extract : "The problem may affect users of Media Manager, such as DB2 and Catalog, and can result in abends, hangs or potential loss of data. Data recovery may be required". You can find the entire description and the PTF you should aply over here.
