Hi Harish,
Before going for the solution, I would like to understand the mechanism of your task list, like -
1. How are you fetching the tasks and displaying the count ?
2. In case a new task is assigned to the user/group how are you updating the current task list ?
3. Once a task is complete how are you removing the task from the task list to update the list ?
4. Are you loading the task list within process portal ?
