+ Xiao I do believe regression is high priority, and I'm very willing to contribute our efforts to improve the stability of RXE :) Yang,Xiao and me tried to reproduce the issues in maillist and we also tried to review the their corresponding patches. However actually we didn't find a unified way something like bugzilla to maintain the issues and their status, and most of them are not reproduced by our local environment. So it's a bit hard for us to review/verify the patches especially for the large/complicate patch if we don't have the use cases.
BTW, IMO we shouldn't stop reviewing other fixes expect recent regressions.
