Yes, I was trying different configurations and it has worked when using mysql-5.5 on ubuntu and mysql-5.6 on centos. Maybe it did get fixed on ACS 4.5.1 as my test environment was with CentOS 6.6 and the default mysql version which is mysql-server-5.1.73-3.el6_5.x86_64. I tried reinstalling different version on the 4.4 branch and all of them exhibited this problem in this mysql version.
