-----------------------------------------------
We are facing the same problem in the 0.90 also when using GZIP. Below is a
snapshot of the 'top' command
{code}
13236 root 20 0 21.9g 21g 12m S 1 68.4 450:56.37 /opt/nn/jdk1.6.0_22

This value we got before the patch was created. After the patch no leak was
found. Anyway precise reports will update tomorrow as today our test clusters
are busy with other task.
Configured heap is 4G for RS.
