Usergrid | Locks | Two million cells per average read

 Hi Usergrid Team,

We are facing OOM and Heavy GC activity on our Cassandra nodes. It seems
the Locks.AstyanaxLocks table is returning close to two million cells per
average read. Please note, this issue is coming up even when no one is
accessing the system.

Our setup is as below:
Environment: Ubuntu 14.04, Tomcat 7, JDK 1.8.0_65 (Oracle)
Usergrid version: 2.2.0 (Master branch, 3rd May, 2016)
Cassandra version 2.2.11 (3 node cluster with RF=3 and LOCAL_QUORUM)

Appreciate the help.
Thanks
Jaskaran
