Thanks for your advice. I have done the same test on version 3.3.0-rc3 and 3.3.0-rc4. For version 3.3.0-rc3, the Oops problem can be easily repeated in 1 to 5 mins. For version 3.3.0-rc4, I have tested around 24 hours, no Ooops is found anymore. The problem I hit is proved to be solved in these patches.
