Subject virtual memory of all cassandra-nodes is growing extremly since Cassandra 1.1.0
Date Wed, 04 Jul 2012 12:13:26 GMT
Hi @all,

since our upgrade form cassandra 1.0.3 to 1.1.0 the virtual memory usage
of the cassandra-nodes explodes

our setup is:
* 5 - centos 5.8 nodes
* each 4 CPU's and 8 GB RAM
* each node holds about 100 GB on data
* each jvm's uses 2GB Ram
* DiskAccessMode is standard, indexAccessMode is standard

The memory usage grows upto the whole memory is used.

Just for information, as we had cassandra 1.0.3, we used
* DiskAccessMode is standard, indexAccessMode is mmap
* and the ram-usage was ~4GB


can anyone help?


With Regards
