Subject Re: Cassandra consume large memory
Date Mon, 18 Jul 2011 06:51:31 GMT
Thank for your response.
Do you talk about virtual memory (column VIRT show in top command)?
But I mention about column RES. In my case, VIRT is 61.8G, RES is 3.2G and
SHR is 1.2G.

JMX show Memory Usage:
Used : 600MB, Commit 2.1G, Max: 2.1G
