Hi, I am using WebLogic 6.1 + SP2 and I have same question.
Here is the WebLogic Problem Solved list:
http://e-docs.bea.com/wls/docs61/notes/bugfixes2.html I assume that WebLogic 7.0 don't have those problem since those problem really caused our servers down and I have applied at last 5 patches on our WebLogic 6.1 server.
Of course, the newer version comes better features. But it might be helpful and practical that you just look at the list and to see what problem you have and could be fixed by newer version or just adding some patches, since you might not use all the features of the WebLogic.
