Infact this is observed in DR itself with below steps

1. Started server
2. Connected to the OM and performed basic navigation (navigating to Account, customer, assets, orders and contacts ) the memory size was at 680M
3. Kept those 2 sessions alive.
4. Delivered a developer workspace to the integration branch. Changes made in the dev Workspace: 2 Applets and 1 BC, just modified comments
5. Opened a third session from another browser to the same OM, after login memory : 699M
6. After the same basic navigation(navigating to Account, customer, assets, orders and contacts): 844M
7. Performed the same basic navigation again on the same session, memory reached to  1.3G
8. Repeated the steps and in short span of time the PID reached 3.3G
9. After Reaching 3.3G PID got crashed.
