TIMESTAMP in TPC-C benchmarks

[yujjjang]

Hi, I have a question when i build and run DBx1000.

When i run 'rundb', CC_ALG=TIMESTAMP with TPC-C benchmark, I found the interested one.
when i change the PERC_PAYMENT value 0.5 to 0 or 0.5 to 1.0, It does work well. (it also works well in YCSB workload).
But the other case doesn't work. (the value 'PERC_PAYMENT' is not both 0.0 and 1.0)

My question is, is the error an algorithmic problem in TIMESTAMP or in other factor?
I've tried to find the error in code, but this problem is really not simple to me.
Thank you.
