Description:
CPU:40Core, Mem:132GB, Disk:300 data + 11* 2T, Network Card: 4*GbE bond, ATS:
5.3.1 or 6.1.1
Recently I found possible memory leak in production host with ATS version from
5.3.1 to 6.1.1, the memory tracker log is as following:

the possilbe memory leak position is in Cache.cc:2490, including new_CacheVC
and free_CacheVC, and memory leak has 41769619456 byte. I wonder some places
forget to call free_CacheVC, but not sure.
