There were some known cache corruption issues that were discussed at WWRUG13. The newer hotfixes (7.6.04, 8.0, 8.1) I believe attempt to address these. We recently applied the Dec 8.1 hotfix and I have not heard any reports of these types of errors. Admittedly these were not originally reported to my team until many had suffered much pain so it is hard to tell if hotfixes actually did the trick.
