Hi. now I’m try to benchmark using the tpcc\_mysql.  
I have some error message in result file.

My configuration is

- OS: CentOS 6.5 (2.6.32-431.el6.x86\_64)
- mysql: 5.6 30
- tpcc\_mysql: how can i check the version?

After the tpcc\_start process, the “error at thread\_main” message printed in result file.  
But it is not appears with mysql 5.6.17.  
Why happen this?
