Hello.
C* have been running without any problem for some weeks but now it
started to consume all available ram.
The cluster have very little data in it. There are no errors in logs, CPU
is not loaded at all, jstack shows no deadlocks, there are 83 threads.
Read/write latency is 1-4ms.
The question is: how to find out where is the RAM used?

We use AWS m1.medium - 3.75 RAM, 1 Core
java version 1.7.0_10
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
C* is started with the following command
/usr/java/latest/bin/java -ea
-javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities
-XX:ThreadPriorityPolicy=42 -Xms1G -Xmx1G -Xmn512M

Thanks in advance.
